Thanks!

IMHO sounds like far less than 1‰ of all CPAN modules might rely on this.


UPDATE:

OK found another use-case, I just recently had the need in my ORG-Parser to distinguish the range delimiters and the range "body" with a flip-flop-operator, like for ORG's "BEGIN/END"-blocks.

This can be simplified (i.e. more DRY), if one has access to the last successful pattern:

DB<114> for(0..99) {print if (/10/../20/ and not //)} 111213141516171819 DB<115> for(0..99) {print if (/10/../20/)} 1011121314151617181920 DB<116> for(0..99) {print if (/10/../20/ and //)} 1020

I think that's a more frequent application, I even slightly remember seeing it in Friedl's book.

But I'd rather prefer an explicit special varą, something like $PATTERN or $&& (in analogy to $MATCH resp. $&) .

Cheers Rolf

1) an special var has the advantage that the regex itself can be accessed, e.g. printed.
