Re: [Haskell-cafe] Map list of functions over a single argument

I'm after a function, sort of equivalent to map, but rather than mapping a function over a list of arguments, I want to map a list of functions over the same argument. The signature would be [a -> b] -> a -> [b], but hoogle didn't come up with anything.

It seems like an obvious analogue of map, so I'm pretty sure I'm missing something (otherwise, I'd just write it myself, and not bother :-))

Can anyone point me in the right direction?

It's rather a small function to bother putting in the libraries, and I think better expressed using map directly: rmap fs x = map ($ x) fs -- David Roundy http://www.darcs.net
