So if I understand you both correctly, we have to continue to support
all perl 5 code forever?

Because that is what I understand you to be saying.

To me this question comes down to a simple technical question: what
language variant does the parser start out expecting before it sees
the "use v7" line?

If we say "perl 5" then we have to support all of perl 5 forever don't we?

Doesn't that kind of er, stand in the way of not supporting perl 5 forever?

Doesn't it make a lot more sense to say "prior to seeing a C<use
v$DIGIT;> statement the parser will be expecting the *latest* variant
of the language"? Isn't the certainty of that the only sane choice if
we are ever to deprecate older variant code?
