Clojurians Log v2

Sorry if this was asked times before. What is the correct way to emulate core.async's alt! on Manifold streams? I'm looking for "takes exactly from one stream" behavior.

https://github.com/ztellman/manifold/blob/master/src/manifold/deferred.clj#L1125

That works only on deferreds, unfortunately

Not on streams

right, and it doesn't appear to have any way to cancel deferreds that are the result of a take on a stream

Exactly

AFAIK, the implementation of alt! is half of core.async's complexity

But I wonder what can be used instead

it is too bad neither core.async nor manifold is built on the ideas from concurrent ml

manifold's notion of deferreds seems to be almost there
