Oh, sure, I saw the patch.  I saw it as a starting point; subsequent
discussion (before my mail, IIRC) turned to the question of providing a
customizeable behavior, so that both ways were available.  In any case,
I assumed that potential customization was so obvious we were clearly
just talking about the question of what the default should be.  I see
now that I should have made that assumption more explicit, however.

Actually, no -- not only do I recognize it, it is the majority use case
for me as well.  I just don't think it's good as a default, that's all.

That's another solution, hmmm, but it seems to me it complexifies the
user interface a bit (it adds another binding in the keyspace, which the
user then cannot avoid encountering when looking at the available bound
commands -- whereas a variable is something they only need to deal with
if/when they go looking for it, read the documentation, etc).  So I'm
not sure which way is better; I think we might be down to the "tyranny
of small differences" at that point :-).

As far as that assertion goes, it is true, yes.  It doesn't address the
keyspace complexity issue.

I guess I'll ponder, and then commit some patch.  It need not be the
final patch, but 90% of the code is the same either way and I'd like to
get that part into the codebase so we can discuss the other 10%.
