I have some monadiccode of the form:
foo >>= something >>= bar >> return ()
HLint is telling me to change this to:
void (foo >>= something >>= bar)
Why is the second form considered better? I actually find the original to be
clearer.

Just to mention, I have seen a plugin for programming in Haskell in
Intellij Idea; I didn't experiment much with the plugin but Intellij Idea
is a good IDE.

In corner cases like this, it really looks like six of one, half dozen of
the other.
In other words, feel free to ignore hlint when you need to. The heuristics
aren't tuned to be 100% perfect.

The vast majority of people use the first form. I guess the second form
would be used if void were in prelude but it isn't, so no one does.

So when is void better?

If you think it looks prettier, then use it. But it is just (\x -> x >>
return ()) under the hood so it makes no difference.

I'm surprised nobody mentioned emacs, I know the emacs/vim divides run deep
but a lot of haskeller make do with emacs, haskell-mode contains what you
ask for (shortcut to ask the type of something to ghci) and much more.
