This is the way it's defined in Haskell - a 'module' export expands to 
all those names in scope qualified with that module name.  There might 
be several different modules imported with that name, and the 'module' 
export would export the contents of all of them.  So I'm afraid you have 
to traverse the whole of the scope.

I suspect we don't do this properly in Haddock, since the documentation 
always contains just a link to the exported module, right?
