> Does Squeak have/support coroutines?
Yes, there are at least three ways you could implement coroutines:
- using Process and Semaphore
- using #swapSender: on ContextPart
- using Continuation from the Seaside package
The actual implementation is left as an exercise for the reader... ;)
Was there a particular use you had in mind?  A lot of what coroutines
might be used for in other languages would be done with block
parameters in Smalltalk...
