`' IIRC it is *impossible* to fully implement nested matching quotes
`' with a regexp.

This was already possible in 5.6, and it even simpler in 5.10.

For instance,

qr [((?:\((?1)*\))*)]

is a regexp to match balanced nested parens.


But the OP isn't asking about nested matching quotes. All he wants is
delimited strings, with escapes.

I'd use Regexp::Common, but it's not hard to come up with a regexp
for a single quote delimited string (untested):

/'[^\\']*(?:\\.[^\\']*)*'/s
