While we're on the topic, what do people think of a related problem,
case expressions over monadic values? I run into this often enough
that it's a pain. I'd like to take
result <- act1
case result of
... -> actN
and drop the bind entirely to get
case act1 of
... -> actN
I know that there are many helper functions and constructs to make
this sort of thing more readable, but sometimes a case expression is a
good fit and the preceding bind just ends up being noisy.
