What's the minimum version of Perl needed to reliably exploit the (?{
code }) feature in regexps?
You can check at <http://search.cpan.org/dist/perl/>. The first
version where pelre documents this feature is 5.005.
Though as far as “reliably” is concerned: it has never lost its
“experimental” status. Even if I doubt that it would be removed
from Perl5 at this point.
Thanks, Aristotle.
After checking that URL, I've confirmed that 5.005 probably *could*
work, but I've successfully tested my module on 5.6.0 and called that
good enough (since I use "our", etc). I've uploaded
Net::IP::Match::Regexp to CPAN.
Yes, I see your point about the experimental status. Well, it's the
only way I could think of to implement varying return values via the
regexp. I'm using only the most basic aspect of the (?{code}) feature,
so I'm safe unless someone takes $^R away from me. :-)
