I wonder if perhaps you're asking about something like this: 
#!/usr/bin/perl
use strict;
use warnings;
# 864348

$_='qwerty erk';
my $pos;

my $foo = $_ =~ s/r/
        $pos=pos(). "\n";
        print pos(); 
        print "\n"; 
        ++( pos() );
        print "\t" . pos() . "\n";
        print($pos . "\n")/gex;

print "Now, outside the regex, $pos";

Output:

3
        4
3

8
        9
8

Now, outside the regex, 8

(Note: as you wrote the one-liner in your previous, you wrote an illegal ref to $_; the $ does NOT need escaping in your one-liner.
... and I'm confused: "G" and "g" come and go in your posts... sometimes one; sometimes the other; and sometimes, not at all.)
