Re: [Omaha.pm] Tighter/cleaner way to do this? map { grep {} } ?

[Jay Hannah <jay@jays.net>]

Ooo... cool. 


Old code:

my @b;
foreach (@a) {
  if (/(gold\w+)/) {
     push @b, $1;
  }
}


New code:

my @b = map { /(gold\w+)/ } @a;


map gets the matches only ($1), not the entire original string.  :)
