I suggest adding this as an orphan instance (Like Show (a -> b)) in a
seperate module (say, Numeric.Function).

In short: It would make 2(x+y) no longer a type error but equivalent to
2. We
would lose a lot of type safety for little syntactic gain.
Btw. before adding more Wat instances please implement the GHC warning about such instances: https://ghc.haskell.org/trac/ghc/ticket/11796 _______________________________________________ Libraries mailing list Libraries@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/libraries
