Sorry I deleted my original comment as I thought it might be too off-topic. Yes, Dynamic C had built-in coroutines :) I think it's hard for me to use threads now because of how convenient a single-threaded main loop with coroutines is. A lot of concurrency "problems" vanish when you realize you as the programmer are controlling the context-switching and that race conditions are implicitly not possible then. I went so far as to write my code so that it compiled in GCC and Dynamic-C to speed up development time (not needing to wait for the 2 minutes it takes to compile and reflash), which meant abandoning all those things and re-implementing them in a cross-platform way buried in a mountain of #ifdefs Although I can't remember all the details now (5 years since I touched that compiler) but I still have a lot of deep seated hatred towards it for reasons I can't remember clearly :)
