Thanks for finding a solution.  It seems to work (at least according to ‘make
check’).

However, I am not pleased by the current state of the
‘specification/package-name->...’ procedures.  They don't compose well,
and are obfuscated by being fragmented across a bunch of modules.  I
don't know if there is much room for improvement but my feeling is that
the brain involvement required for implementing the '@' thing was far
too high compared to the actual task.

I have left the emacs interface untouched.
