Recently, I came accross this expression: [ x + y | x <- xs | y <- ys ]
As far as I can see (Haskell Report), this is not allowed by the haskell 98 standard. So I assume it to be an ex- tension. Where can I find information about this?
It's not Haskell 98, but is implemented in GHC and Hugs (with extensions turned on).
As far as I can tell ghc 5.04 accepts this without complaint. Is this a bug, or should I pass some argument to turn extensions off? Jón -- Jón Fairbairn Jon.Fairbairn@cl.cam.ac.uk
