It's not clear to me how to check this at the `Cmm` level, how do we determine what is top level? Perhaps you meant to check the invariant in `CoreLint`? I'm having to tweak a few of the checks there anyway that expect all top-level binders to have lifted types. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8472#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
