Hello haskell-cafe, now i'm reading Haskell' proposals and found that these two things considered as different:
http://hackage.haskell.org/trac/haskell-prime/wiki/ExistentialQuantification http://hackage.haskell.org/trac/haskell-prime/wiki/PolymorphicComponents can you please explain me what is the difference between data Ex = forall a. Num a => Ex a and data Po = Po (forall a. Num a => a) ? -- Best regards, Bulat mailto:[EMAIL PROTECTED] _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
