example:
realize that qq/end/ does not represent a matching "end"?
What happens then when it sees something like a double variable
interpolation as in $$foobar? ;)
The delimiter does not have to be $$. It can be
$any_unquoted_identifier_without_a_dollar_sign$.
the lexer says:
/* $foo$ style quotes ("dollar quoting")
* The quoted string starts with $foo$ where "foo" is an optional string

dolq_start [A-Za-z\200-\377_]
dolq_cont [A-Za-z\200-\377_0-9]
dolqdelim \$({dolq_start}{dolq_cont}*)?\$
So for a plperl function you just use something like $func$ at each end.
