Re: [Haskell-cafe] proposal: point free case expressions

5 Nov 2009

      ...
So we could write:
...
myFunc = anotherFunc $ case of
                         Left err -> print err
                         Right msg -> putStrLn msg
A minor syntactical addition, a big win!
+1.

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.
