While I refactored the ghc code base to declare LANGUAGE pragmas locally, rather than via -X-flags on the GHC commandline, I've noticed 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?
