It's of about the same implementation complexity as "valuable"
extensions like N>R NR>.  If your current locals implementation makes
it too complex to have locals in quotations, just support locals
without quotations.  Hopefully at some point you will redesign your
locals implementation to remove some of the limits, but quotations
without locals are much better than no quotations.

I think that it is much easier to implement quotations than to keep
supporting return-stack tricks (which you are prepared to do).

Sure, it is syntactic sugar.  Sometimes syntactic sugar is valuable to
have.  In this case it is.  We don't want bitter programs, do we?

Do I understand you correctly?  To save a few lines of code in every
system, every program that needs quotations should include these lines
for all systems?  How does this help?  If I understood you
incorrectly, what did you mean?
