While I refactored the ghc code base to declare LANGUAGE pragmas

there were a couple of places where NondecreasingIndentation grammar was used.
What's the current consensus on the use of NondecreasingIndentation? Is
its use still encouraged?
I like it for things like
do
...
if exit_early then return () else do
... more stuff ...
Without NondecreasingIndentation this creeps to the right, which isn't
a good use of whitespace.
I see, so NondecreasingIndentation is mostly used to simulate
early-returns?
I suspect that's what I mostly use it for. Simon PJ likes braces and
semicolons instead :-)
It's not a big deal, but I don't see a strong argument for getting rid
of it either.
Cheers,
Simon
