[Omaha.pm] pushing arrays onto arrays?

[Jay Hannah]

Nope. :)
 
What you expected would happen if you did "push @a, \@b".

Wow.

I always thought that if you "push @a, @b", the @b would end up as some
type of reference in the @a array.  I guess not.

#!/usr/bin/perl

use strict;
# Push @b stuff onto @a separately.
#
my @a = qw(1 2 3);
my @b = qw(4 5 6);
foreach (@b) {
  push @a, $_;
}
 
print join " ", @a;
print "\n";

# push @b onto @a.
#
my @a = qw(1 2 3);
my @b = qw(4 5 6);
push @a, @b;
 
print join " ", @a;

exit;
