I tried to compile the Gtk2Hs code generator with hugs (September 2006)
 and it complained about this bit of code:

 {{{
 extractAPI :: Xml.Document -> API
 extractAPI (Xml.Document _ _ (Xml.Elem "api" [] namespaces) _) =
 }}}

 The message is:

 {{{
 ERROR "./Api.hs":156 - Illegal type "Document -> API" in constructor
 application
 }}}

 Commenting out the type signature suppressed the error.

 The problem seems to be a mixup in what namespace {{{Xml.Document}}} is
 being looked up in. There is both a type {{{Xml.Document}}} and a
 constructor {{{Xml.Document}}}. The type name seems to be masking the
 constructor name. It may also be because it's a qualified import. I don't
 know, I've looked into that any further.

 The Gtk2Hs code generator is here:
 http://darcs.haskell.org/gtk2hs/tools/apiGen/

 You only need the Api.hs module to reproduce the error, though you would
 need all the .hs files in that dir to get the whole thing to run of
 course.
