-rename- as such places absolutely no restrictions on the use of
locals in -rename- commands for the very simple and very fundamental
reason that all macro references are interpreted before -rename- gets
to work. -rename- never sees any macro references, just their
interpretations as macro contents.

That said, let's emphasise that -rename-'s language is based on
extensive use of wildcards.

Either way, the heart of David's question seems to be whether a common
stub is needed for -rename- to work well, if at all, and the answer is

-rename- can be used with a first argument as general as (*), meaning
all variables, so there are no presumptions on the structure of
variable names.

Otherwise I think we need to see concrete examples to comment on
apparent difficulties here.
