Feature request for Haddock: cross-module name reference

Another little wish for Haddock: It is currently possible to reference names in scope via 'foo' and modules via "bar.baz.blah". But sometimes it would be convenient to reference a name in another module without importing it just for documentation purposes. Further note that circularity in documentation is not uncommon. So a markup for this task would be very nice. I'm not sure if the name should always be rendered in a fully qualified way, because this tends to clutter up the documentation. On the other hand it would be better in printed (i.e. non-mouse-clickable) docs. Hmmm... Does this make sense? Cheers, S.
