FWIW, I really dislike whitespace-significant syntax. f ! x should

What about `elem`? I don't think anyone would argue that ` elem ` makes
sense.
Prelude> 1 ` elem ` [1..10]
True

True
backticks are part of the context-free syntax, not the lexical syntax
(as they should be!). I'm of the opinion that the lexical syntax should
be as simple, and as far as possible everything should be pushed into
the context-free syntax.
Cheers,
