Compatible union type. Values of this type are represented in memory similarly to their JSON representation (i.e. inside an object with single key the name of the contained type). This is not ideal, but is the most efficient way to unambiguously support all unions. Here are a few reasons why the wrapping object is necessary: + Unions with multiple number types would have undefined behavior, unless numbers are wrapped (either everywhere, leading to large performance and convenience costs; or only when necessary inside unions, making it hard to understand when numbers are wrapped or not). + Fixed types would have to be wrapped to be distinguished from bytes. + Using record's constructor names would work (after a slight change to use the fully qualified name), but would mean that generic objects could no longer be valid records (making it inconvenient to do simple things like creating new records).

Factory-based emitter. This emitter doesn't keep a persistent connection to the server and requires prepending a handshake to each message emitted. Usage examples include talking to an HTTP server (where the factory returns an HTTP request). Since each message will use its own writable/readable stream pair, the advantage of this emitter is that it is able to keep track of which response corresponds to each request without relying on transport ordering. In particular, this means these emitters are compatible with any server implementation.
