[Haskell-cafe] Find unused exports

[Jason Dagit]

Hello,

Has anyone already made a tool to check if exported functions, data
constructors, types, etc are unused within a set of modules?

For my usage it would probably suffice if the tool only compared
import lists against export lists as we compile with -Wall and 99% of
our imports say exactly which names are imported (and that last 1%
could easily be fixed to say as well).

If the tool doesn't already exist is there an easy way to approximate it?

Thanks,
Jason
