So I want to be able to say something like:

Well it might indicate to use a different function while evaluating the expression. Still not a good example, I know. Best, Ozgur

OK I back up. I justed wanted it to happen for a moment :) You're right, ambiguity in parsing and a lot of whitespace-dependency are things to avoid. Best, On 4 June 2010 14:25, Ketil Malde wrote:

I like to think that Haskell is a language where aesthetics matter. So, in my opinion this is indeed a horrible consequence.

I find mixing of symbols and letters in identfiers to be in itself aesthetically inferior, and there's already more than enough whitespace-dependent parsing warts in Haskell.
