Comment(by michalt):

 Thanks for reporting! However, I can't reproduce this. For HEAD I get:
 {{{
 > ~/dev/ghc-clean/inplace/bin/ghc-stage2 -rtsopts Test.hs
 [1 of 1] Compiling RewriteProblems  ( Test.hs, Test.o )
 Rule fired: rewrite/static
 Rule fired: rewrite/class
 }}}

 and for GHC 7.4.1:

 {{{
 > ghc -rtsopts Test.hs
 [1 of 1] Compiling RewriteProblems  ( Test.hs, Test.o )
 Rule fired: rewrite/static
 Rule fired: rewrite/class
 }}}

 So both rules fire. Have you tested with GHC 7.4 or HEAD?
