Hello all,
Wouldn't it be nice if we could write point free case statements?
I regularly find myself writing down something like this:
myFunc = anotherFunc $ \x - case x of
Left err - print err

A minor syntactical addition, a big win!

If we're counting increments, should add in previous instances of the
same proposal - Andrew Pimlott Sep 2005 on haskell-cafe, at least.
I agree with Stefan Monnier, might as well allow pattern alternatives
in lambda expressions - essentially the same idea and allows multiple
case
