Yes, I hadn't thought of that. Yay again.

Absolutely.

That would become the sole use for the funky chars.
And since the type of each var is known, you'd only need one
funky char. In effect, its semantics would change to purely
one of forcing the recognition of an identifier where otherwise
a string literal would be understood.
my @things; # declare that things is an array
print "things are $things";
# second occurrence of "things" here is taken as a variable name.
# its type -- array -- is already known.
