Subject: Make rules available in RHS
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=dd09857f4b1bb6375ca807ca06f13ab0625e463d

Make rules available in RHS

After some earlier re-factoring, the code that was carefully trying
to make RULES available in a function's own RHS was plain wrong.

This commit fixes it.  Some programs should go faster!
