Oh, I see. No wonder this conversation has been confusing.
The mistake, I think, is when we assume that we speak the same language.

To everyone else: From the lack of other response, should I assume
that my memory of this usage of "multimethod" for "sub with :multi" is
incorrect?
. . .
A particular sub object that's stored in a MultiSub is a "variant" of
the multi (whether it's a multisub, multimethod, or multivtable).

Urp. I have been calling these "methods" for 15 or 20 years now (since
whenever the Lisp world went to MMD), so please bear with me while I
change gears.
FWIW, the documentation has about 100 hits to the word "variant", but
only two (AFAICS) refer to MMD, both of them in a single paragraph in
docs/book/ch07_architecture.pod. The other hits are talking about
opcodes and vtable operations. (Plus a hit I don't understand in
docs/pdds/pdd15_object_metamodel.svg, which doesn't seem to address MMD
at all.)
