Haskell *will* tell you errors that don't make any sense (at least GHC
errors) when you don't have things like this done properly

do x <- foo
y <- bar

the y <- bar must be directly under the x on the previous line or it's a
syntax error, and the error you get from GHC is "the last statement of a do
construct must be an expression"

not

"dude, you suck at indenting code, and should have used Emacs to keep track
of it, because nothing else does the job right".

Luckilly Haskell will let you ignore "layout" and do the following:

do { x <- foo
; y <- bar }

However, I don't see enough of this style code to feel comfortable writing
anything I'd plan to share with anyone and expect them to feel ok reading
it.
