When you type this into GHCi:
{{{ λ> let a :: forall a b. (Num a, Num b) => (# a, b #); !a = (# 1, 2 #) }}}
you get this error:
{{{ You can't mix polymorphic and unlifted bindings !a = (# 1, 2 #) Probable fix: add a type signature }}}
I'm confused. That's not an unlifted binding! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13311#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
