Don't. It might be a lot of work to convert from Perl, but it's even more work to parse Perl. If you insist, you probably should start by taking a look at
String::Interpolate (uses a
Safe compartment to confine the interpolation to specified
VAR => $value pairings) and
PPI (a Perl parser).
quoted_string: '"' m{(([\\]"|[^"])*)} '"'
I hope your never have spaces after the first """ in the text you are parsing, or did you change <skip>?
It's best to avoid separating a token into multiple items. It's rarely necessary or even easier.
