Re^2: Driving the Engine right off the road

If perl supported variable length lookbehind, you could use a lookbehind at the end:

Just a data point but Perl has limited variable length lookbehind as an experimental feature since version 5.30, with support for up to 255 characters. https://perldoc.perl.org/perlexperiment#(Limited)-Variable-length-look-behind

See also https://perldoc.perl.org/perl5360delta#Variable-length-lookbehind-is-mostly-no-longer-considered-experimental I do wish it could work in even more cases, like where the beginning point is known (e.g. `(?<=\A...)` or with `\G`) or something like `(?<=...\1...)` where the length is known when running that part of the regex even if not when compiling it.
