Hey,
Thanks for all the suggestions. I was hoping that there was some
uniform
pattern that would extend to n arguments (rather than having to use
liftM2, litM3, etc. or have different 'application' operators in
between
the different arguments); perhaps not. Oh well :)
Sure you can! What you want is Control.Applicative, not Control.Monad.
(<*>) is the generic application you're looking for:
> pure (+) <*> [1,2,3] <*> [4,5,6]
[5,6,7,6,7,8,7,8,9]
Note that pure f <*> y can be shortened to fmap though, which
Control.Applicative defines a handy infix version of:
> (+) <$> [1,2,3] <*> [4,5,6]
[5,6,7,6,7,8,7,8,9]
Hope that provides what you want
Bob
