Hi,
I have a module A that re-exports module B, and module B contains only class
instances. Since I'm using -Wall, I get this warning about module B
exporting nothing. Is there a way to disable this particular warning, since
it is unnecessary in this case? No mailing list messages or GHC
documentation has told me what to do.
Well, the warning is right that you don't need to re-export
module B: instances are implicitly exported. So you could
just remove the export of "module B", unless there's a
reason to export it (such as, you might add some exported
functions or data types to it later)
