This module is an adaptation of Chris Hawblitzel and Erez Petrank's
simplified mark-sweep collector from the POPL 2009 paper
"Automated Verification of Practical Garbage Collectors"
While this module states and proves the same properties as the paper,
its implementation is currently still quite high-level, e.g, it
uses lots of recursive functions instead of while loops with mutable
local variables. Going lower level with this module is work in progress.

This module is an adaptation of Chris Hawblitzel and Erez Petrank's
simplified mark-sweep collector from the POPL 2009 paper
"Automated Verification of Practical Garbage Collectors"
While this module states and proves the same properties as the paper,
its implementation is currently still quite high-level, e.g, it
uses lots of recursive functions instead of while loops with mutable
local variables. Going lower level with this module is work in progress.
