Comment:
Here is a patch that implements this functionality (with [~] meaning never
automatically fire), as well as a patch to the testsuite to verify the
parser works.
I've built HERMIT against head (with this patch applied) and verified that
we can still use RULES that are marked to never fire (at both ends of the
optimization pipeline). As an aside, all the packages required by HERMIT
compiled fine, so it doesn't seem to break any existing code. I've also
run the ghc validate script, with no extra unexpected errors.
