Hello everyone, (I am posting here because I could not find a dedicated core.async group)
recently I made a rather obscure bug-report (ASYNC-29). As a comment Rich Hickey stated that <!! and >!! should not be used in library code. I can now reproduce the same problem without <!!/>!! by simply derefing 50 undelivered promises in dedicated go-blocks (dotimes [_ 50] (go @(promise))). After that it is not possible to take from channels inside go-blocks. Now I can imagine that using promises in go-blocks is not exactly doing what they are designed for. I suppose that using promises within go is not supported. However I wonder what my options as a library creator are when I want to write a function that is designed to wait until it has taken a value from a channel. The only way I can see is to write a macro instead of a function, two versions. One using <!, designed for use in go-blocks, one using <!!, designed for use outside of go blocks. Otherwise, I don't see any possible way to get a value from a channel and returning it. Or am I missing something? Is it simply unidiomatic to return a value from a channel from a function body?
