;;;; Managed-floats
The type ` tl : managed - float ' has been added to TL to provide low level
;;; support for a type that can hold double-floats or a pointer to an object.
;;; The memory for these locations may be allowed to overlap if that aids in
;;; making these objects as small as possible. The goal of this object is to
;;; store a floating point value as efficiently as possible while they are
;;; allocated and to store a pointer to the next managed-float in a resource
;;; pool while they are reclaimed. The operations available on managed floats
;;; are `tl:make-managed-float', `tl:managed-float-value' (which is setfable),
;;; `tl:managed-float-next-object' (which is setfable), and
;;; `tl:managed-float-p'.

This means that in development Lisp images, we must always use char to

this operation will overwrite whatever object arbitrarily follows it in
memory.
Let the C compiler multiply the start args by sizeof(Obj) as a
side-effect of adding them to the Obj* arrays.
The macro `tl:replace-uint16-arrays' is a version of replace optimized for
being copied, or else this operation will overwrite whatever object
arbitrarily follows it in memory.
Note that tl:fill-string (the only caller for fill-string-1) guarantees
that I can eval the start argument twice.
Note that the existing type coercions will do exactly the right thing with
this.
We have no fast implementation for initial-contents, so we should always
complain when it is used, unless the user has already admitted that this
is fat-and-slow.
Some varieties of our arrays have fill-pointers always, and some don't.
If they ask for a fill-pointer on an array type that doesn't support it,
complain here, else just do the default thing.
Managed-floats
support for a type that can hold double-floats or a pointer to an object.
The memory for these locations may be allowed to overlap if that aids in
making these objects as small as possible. The goal of this object is to
store a floating point value as efficiently as possible while they are
allocated and to store a pointer to the next managed-float in a resource
pool while they are reclaimed. The operations available on managed floats
are `tl:make-managed-float', `tl:managed-float-value' (which is setfable),
`tl:managed-float-next-object' (which is setfable), and
`tl:managed-float-p'.
Streams

existing structures. This works fine as long as the memory meter functions
(which are rarely called) are not declared side-effect free.
The macro `set-list-contents' and `set-list-contents*' will modify a list
such that it contains as elements the new contents passed as the rest
etc. in that it will not traverse the conses of a list more than once. It
returns the passed list. This macro is used by the implementations of

functions being defined here can be translated. This macro is defined here
Symbols
This section implements the lowest level primitives for symbols. Many other
features, such as interning and gensyming, are implemented in
tl/lisp/packages.lisp.
The `make-empty-symbol' mallocs and type tags the memory for a symbol, but
does not yet install a print-name or any other characteristics. They all
The translated form `set-symbol-type-tag' takes a symbol and installs the
appropriate type tag onto it. This is needed to initialize C symbol
structures that were allocated in arrays, i.e. the constant symbols of a
translated file.
The macro `fboundp' takes a symbol and returns whether or not the
function takes only symbols and not generalized function names.
fill-pointered strings, this is especially a problem. So, within the base
Lisp environment, make sure that all strings given to make-symbol are in
fact simple-strings.

returns a new package with that name. If a package with that name already
exists, this function signals an error.
that it signals an error when given a package object instead of just
returning it. This macroexpansion will work around that bug.
The macro `typep' implements runtime type checking for Lisp objects but has
the restriction that the type argument must be a constant.
Note that tli::type-tag is not a proper macro, and can evaluate its
argument multiple times.
Perform some optimizations when negating an argument. If this is a not of
a not, just return the argument to the inner not. If this is a not of a
c-equality-expr, replace the argument with a new c-equality-expr using the
opposite equality string. Otherwise, just negate the argument.

The following forms implement operations for fetching the integer values of
object pointers. These are used for printing and for computing hash numbers
of objects.
The translatable form `pointer-as-fixnum' returns the value of the pointer

that this cannot happen. In any case, the returned value is more than
adequate as a hashing number for the given Lisp object. If we had a garbage
collector that could relocate items, this could cause problems, but we don't
so it can't.
Machine Type
The function `get-platform-code' returns an integer which identifies the
currently running system. See code in tl/lisp/tl-util.lisp for how to add
further machines to this set.

| A database instance on a schema. Contains a presentation, an algebra, and a decision procedure.
| True if the type algebra is empty, which approximates it being free,
which approximates it being conservative over the typeside.
| Just syntactic equality of the theory for now.
| A dynamically typed instance.
| Checks that an 'Instance' satisfies its 'Schema'.
| Constructs an algebra from a saturated theory with a free type algebra.
Needs to have satisfaction checked.
-------------------------------------------------------------------------------------------------------------
Initial algebras
| Computes an initial instance (minimal model of a presentation).
Actually, computes the cannonical term model, where the underlying elements
of the carriers are equivalence class of terms modulo provable equality
The term model is constructed by repeatedly adding news terms to the empty model
until a fixedpoint is reached.
| Assemble Skolem terms (labeled nulls).
------------------------------------------------------------------------------------------------------
Instance syntax
--------------------------------------------------------------------------------------------------------------------
Literal instances
-------------------------------------------------------------------------------------------------------------
Basic instances
| The empty instance on a schema has no data, so the types of its generators and carriers are 'Void'.
| Pivot an instance. The returned schema will not have strings as fks etc, so it will be impossible to write a literal on it, at least for now.
