A simple alternative to if would be:

 options = [ ("foo", f1 . f2 . f3)
           , ("bar", f1 . f3 )]

and then "lookup param options". I don't know if this is what you're
looking for, though.


Thanks!
Yes, this is what I need - simple and easy. Yet, how function application will work in this case ?
I mean after lookup returns me a composition ... need to check what type will it be.
