module system bug

[Iavor S. Diatchki]

hi,

i seem to have run into a module system bug, which is illustrated by the
following example:
module A where
    data T = T

module B where
    import A hiding (T())  -- note the parens after T
    v = T

Hugs complains that "T" is an undefined constructor.
This would be the correct behaviour if T didn't have the
() after it, as both the type and the constructors by the name
T should be hidden.  however, the parens indicate that
the type/class T should be hidden, and also all the constructors listed
in the parens.  since the constructor T is not listed, it should not be
hidden.  basically, if a name has parens after it, it always refers to a
type/class.

this is not a big thing, but is ocasionally useful, and more
importantly, it is nice when one can load a program with both GHC and
Hugs, which i am glad to say happens more and more often.

bye
iavor
