[Haskell-beginners] How to select items from one list depending on another

[Ozgur Akgun]

If only ParallelListComp<http://hackage.haskell.org/trac/haskell-prime/wiki/ParallelListComp>supported
filters.

list3 = [ b | a <- list1
            | b <- list2
            , a /= 0
        ]

But it doesn't, so this is an entirely unnecessary post :)

Best,
