Do you have any reference for that use of infixing constructors by start their name with ':'? That's interesting, and I didn't know about it.

sum (x:xs) = x + sum xs sum [] = 0
I think that only counts as the origin of the idea; isn't :-prefixed infix constructors a ghc-ism?

That link is for type constructors, not data constructors; for data constructors, go to http://haskell.org/onlinereport/lexemes.html and search for `Operator symbols'. (The Haskell 98 Report seems to not have internal anchor tags for hot-linking, unfortunately). jcc
