It fails with GHC 7.10 as well, so I'm not sure it ever worked...
What do you mean? It works fine with GHC 7.10.3: {{{ $ /opt/ghc/7.10.3/bin/ghc Bug.hs -fforce-recomp [1 of 1] Compiling Document.Phase.Proofs2 ( Bug.hs, Bug.o ) Bug.hs:60:10: Warning: No explicit implementation for ‘id’ and ‘.’ In the instance declaration for ‘Category LatexParserA’ Bug.hs:61:10: Warning: No explicit implementation for ‘arr’ and ‘first’ In the instance declaration for ‘Arrow LatexParserA’ }}} Aside from some warnings, of course, which are due to minimizing the program down so much. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13547#comment:27 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
