Re: Pass Arrays to a subroutine

I like named params

mysub({ a1 => \@array1, a2 => \@array2 });

sub mysub{
   my ( $argref ) = @_;  # brackets matter

   # ref to @array1 is @{ $argref->{a1} }
   # ref to @array2 is @{ $argref->{a2} }

I always used to accept my params within a hashref, but in the last year or so, I've changed to just using a straight up hash instead. I feel it makes the interface a tiny bit cleaner: `mysub(a => \@array1, b => \@array2); sub mysub { my %params = @_; print "$_\n" for @{ $params{a} }; }` [download]	[reply] [d/l]
