Post #1864454

Thus Unicon and Object Icon are the better implementations, when it comes to co-expressions. Unicon still uses stack-switching, and Object Icon uses what-I-haven’t-yet-examined. (Possible methods are numerous. One could go so far as to separately compile to C and use Cheney-on-the-MTA, or compile to GNU C and use computed goto.) If you want threads in Icon, ADD THREADS! Do it as a foreign library, if necessary.
