Re: [Haskell-cafe] Is 'flip' really necessary?

Excerpts from aditya siram's message of Sun Jul 25 17:13:16 -0400 2010:

Eta-reducing is nice, and sometimes it makes code more readable. But 'flip' is one of those functions that always seems to hinder rather than help readability, conversely factoring out flip always makes code easier to comprehend. I don't see a need for its existence - maybe I'm missing something and more experienced Haskellers can comment.

An interesting alternate spin on flip is infix notation combined with partial application, such as: (`foobar` 3) which is equivalent to \x -> foobar x 3 I frequently use this, although the jury's out on whether or not it's more readable. Cheers, Edward
