Thanks, now fixed. --sigbjorn ----- Original Message ----- From: "Iavor S. Diatchki" <diatchki@cse.ogi.edu> To: "hugs-bugs" <hugs-bugs@haskell.org> Sent: Thursday, February 13, 2003 10:15 Subject: module system bug
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
