Also, is cond the best name for the suggested function? If we don't expect anyone to really use it without the sugar, we could name it whatever weird thing so as to break as few existing programs as possible. It would make explicit import a bit more akward though. But I suspect that if this function did exist in the Prelude, people would start using it a lot.
That's true, I would like to use it. I plead for adding it to Prelude, whether the if-syntax becomes rebindable or not. I like to use (zipWith cond) for composing two lists depending on a key, or (uncurry . cond) as a choice between fst and snd, or the already mentioned 'select' command (foldr (uncurry cond)).
Does anyone have any better suggestions, or is cond the name of the day?
I like the similarity to "if". However if_ or if' are too un-preludish. :-) ifElseThen is probably too long. 'cond' is acceptable. 'provided' too.
