Yes, but that's no more an issue than it is in Perl, where the same $n
variables are globals. The issue with dollar quoting is that you can
put anything between the dollar signs. So if you have two $variables,
they can get in the way. Potentially. But perhaps the lexer and/or
Parser won't be confused by that, Tom?
I'd sure love $, as it's like shell, Perl, and other stuff.
Best,
