BTW, do you withdraw comment:25?
Well, the addition of that `ensureEqTys` did contribute a couple percent to the total compilation time (with `-dcore-lint`) in my test. If it's useful we can keep it; I don't understand what kind of substitution `le_subst` Core Lint is carrying around, so it's unclear to me whether this is actually testing something about the program being compiled or testing the consistency of Core Lint itself. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13220#comment:32 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
