I have to write:
do { x <- getSomeNum y <- anotherWayToGetANum return (x + y) }
even if the computation of x and y are completely independant of each other.
I too have really missed a "parallel composition" operator to do something like the above. Something like do { { x <- getSomeNum || y <- anotherWayToGetANum} return (x+y) } Actually, that syntax is rather hideous. What I would _really_ like to write is do { (x,y) <- getSomeNum || anotherWayToGetANum return (x+y) } I would be happy to tell Haskell explicitly that my computations are independent (like the above), to expose parallelization opportunities. Right now, not only can I NOT do that, I am forced to do the exact opposite, and FORCE sequentiality. Jacques
