Since it is an ordinary haskell function, it is something you can look
up with Hoogle:
It is used for function composition - for example if you wrote a function:
> myFunc x = func1 (func2 x)
you can re-write this to:
> myFunc = func1 . func2
It's useful to cut down on parenthesis when you have a chain of
functions taking one argument.
