Function arguments in Perl

a.k.a. URGHHH...

The three ways you want to remember are:

  1. If you don't know exactly what's coming, roll it all in a hash:

    sub perlFunc {
  my %args = @_;
  print $args{what_was_that_again};

  return(%args);
}

  2. Or, if you do know what's coming:

    sub otherPerlFunc {
  my ($what_was_that_again, $oh_yeah, $never_mind) = @_;
}

  3. And finally, if it's a single parameter you might as well just:

    sub oneMorePerlFunc {
  my $singleValue = shift;
}
