Interesting counterproposal.  I'm not sure whether any of the proposals on
the table really do what's needed for e.g. case-insensitive namespace
handling.  I can see how all of the proposals so far allow
case-insensitive reference name handling in the global namespace, but
don't we also need to hook into the local-namespace creation process to
allow case-insensitivity to work throughout?
