[Haskell-cafe] searching a function by providing examples of input/ouput pairs

Sounds great!

Here are a few feature requests:

The I/O pair ([-1,4,-6],[1,4,6]) could yield "map abs" as a suggestion :)

The pairs ('a',False) and ('*',True) could yield "not . isAlpha" etc.

I realize that this (at least the composition part) will probably
increase complexity beyond what's acceptable...
