In writing up the RFC on removing/fixing $[line noise here] variables,
I've decided to leave out the following suggestion:

The renaming to use hashes or module-form variables is not intended
to *change* the meanings of the variables, it's an attempt to seize
the opportunity to go to a more rational naming structure. The
scoped/localizable use of those variables would potentially be a
major change. Rather than mix them together, I'd prefer to see
scoping/localizing broken out into a separate RFC. Have at it, folks. :-)
