This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
The library allows you to allocate memory in a region yielding a
regional pointer to it. When the region terminates all pointers
are automatically freed. Most importantly, a pointer can't be
returned from the region. So it's impossible to reference
unallocated memory.
The primary technique used in this package is called "Lightweight
monadic regions" which was invented by Oleg Kiselyov and
Chung-chieh Shan. See:
