RE: qualified class name in instance decl

[Sigbjorn Finne (Intl Vendor)]

Hugs98 doesn't support qualified method names in instance
decls (as was reported here a couple of weeks ago). 

In the event you're seeing these qualified method names
in HaskellDirect generated source, there's a workaround just
to accommodate Hugs users; compile the IDL spec with
-fno-qualified-instance-methods (see HaskellDirect user
manual).
