           Summary: Ability to reference 'variables' from regexp
           Product: PCRE
           Version: 8.10
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: wishlist
          Priority: medium
         Component: Code

In Perl, one can use $var in regexp and usually the variable reference will be
expanded.

It would be very helpful in some situations to allow PCRE to reference such
external variables too.
The way I see it, without (seemingly) breaking backward-compatibility, is to
make some way to set values of 'named subpatterns' before pcre_exec(), so they
can be referenced using existing \k{name} syntax. Surely encountering
subpattern with same name inside of pattern would take precedence.
