The problem:
liftTup f (a, b) = (f a, f b)
of the signature
liftTup:: ?? -> (a,b) -> (c,d)
Again, it is possible to write this in Haskell with common extensions

Toolkit. It covers nearly all widgets and thus provides a stable

A Linux ix86 rpm package built with ghc-6.0.1 and gtk2-2.2
is available too now.
