Personally I think function composition is what Haskell is all about and it is absolutely essential that the syntax for it be lightweight. If we think using . as qualification as well as composition is confusing, I'm much more inclined to say using it as qualification was a mistake.
The comment on the wiki page about $ being more common in reality is not even close to true for my own code, and I don't think I'm unusual in that regard.
Agreed on both counts. Personally, I'd much rather have name qualification and record selection use a different character than to remove (.) as composition. And replacing (.) with some abomination like `o` is unthinkable. As for the selector character, I'm partial to # but that would clash with MagicHash. -- Live well, ~wren
