   In other words, any improvement that tries to reduce the
   redundancy in identifiers will require corresponding
   improvement in our tools to infer the now-implicit
   information.

Right.  Sez Alan Perlis:

 Wherever there is modularity there is the potential for
 misunderstanding: Hiding information implies a need to
 check communication.

so the onerous activity here is the "check communication".
I would argue that the current FOO- scheme, being merely
convention, is actually more needful of inference than the
proposed FOO:: scheme.  If modularity is directly supported,
we (programs and humans, both) can turn from heuristics to
algorithms, w/ corresponding reduction in worry and angst
that the "check" is incomplete or incoherent.

That said, my experience (largely positive) is entirely w/
Guile Scheme modules, and i imagine that Emacs' modules would
be similar.  I don't know how Common Lisp does it -- maybe
someone who knows both systems could post a comparison?
