Too bad it has a different heap per thread. If I want to extend a C (or rust) posix-multithreaded program, it means I can't easily use gluon to access the state of my program (which requires accessing posix-multithreaded protected variables in the normal heap). Same thing that makes Lua useless to simply extend actual, pre existing C programs. Anyway, I'm still happy to see that more modern languages than algol have gained enough influence than the choice of type system, type inference and non C like syntax is not frowned upon anymore.
