Hello, My question/wish is maybe naive, but anyway: Is there a library (not a language extension, like Concurrent Haskell, Glasgow Parallel Haskell, ...) enabling to run two functions in parallel, possibly in cascade? Something like:
testAll (threadStart f1 (threadStart f2 f3))
where threadStart :: a -> b -> (WillBe a, WillBe b) where type WillBe is something like Maybe, but changing within a time (mutable values) ~ Processing, Just a, Nothing
testAll (Nothing,p) = putStr "No result for f1" >> testPair p testAll (l,(Nothing,r)) = putStr "Noresult for f2" >> testPair (l,r) testAll (l,(ll,Nothing)) = putStr "No result for f3" >> testPair (l,ll) testAll (Just a,p) = putStr ("res of f1: " ++ show a) >> testPair p ...
testPair ~ about the same like testAll
Probably the explanation is not too clear and what I wish is out of the language scope (not really functional), but I would appreciate something like that. Is there something like that for Haskell/Hugs? Thx for any ref. Dusan
