Stuff with the Perl Foundation. A couple of patches in the Perl core. A few CPAN modules. That about sums it up.

Just what the (code) doctor ordered

[ #34781 ]

After noticing a bunch of duplicated code, I realized that a particular value which needed to be munged only if it was set could be refactored as follows:

$message &&= $cgi->p($message);

I always forget about that construct, but when you need it, it's great!

  • That is so cool and useful, why have I not seen it before? I must re-read my Perl books, I must have missed tonnes of stuff like that.

    • In 5.10, I don't think there's going to be a corresponding feature for this:

      $value //= $default;

      You still have to write:

      $value = $cgi->p($value) if defined $value;

      • This is one of the Perl 6 ideas that everyone wants back-porting I think.

        I see that &&= is explained on page 92 of my Programming Perl 2nd edition. Not coming from a c background I missed the utility of some of these.
