[perl #115214] re::engine seems to fail supporting \G

Is this actually a Perl bug?

https://metacpan.org/module/re::engine::RE2 says:

"Fallback to normal Perl regexp is implemented by this module. If RE2 is
unable to compile a regexp it will use Perl instead, therefore features
not implemented by RE2 don't suddenly stop working, they will just use
Perl's regexp implementation"

If you want to avoid (and detect) that behavior, you can use the -strict
=> 1 pramga.

mhorsfall@Fireforge:~$ perl -E 'use re::engine::RE2 -strict => 1; say
"OK" if "abc\n" =~ /\Gabc$/'
invalid escape sequence: \G at -e line 1.
