 In the course of a project, I had an idea that would allow less cumbersome
 use of cases in anonymous functions. Here's a simple example of what I'm
 proposing:

 {{{

 (\x y | x > y -> x
       | otherwise -> something else)

 }}}

 Currently, the only way to accomplish this is with if() then ... else
 syntax or the use of the MultiWayIf and LambdaCase extensions. The syntax
 I've proposed here matches with existing anonymous function syntax and
 doesn't conflict with any other GHC syntax. This would greatly improve the
 readability of complex anonymous functions.
