in reply to 2D arrays & mo' better blues

It doesn't print what each x,y coordinate is set to, but it does the same as your code: 
use strict;

my @alpha = ("a".."z");
my @outtie;

# INPUT
push @outtie, [ @alpha ] for @alpha;

#OUTPUT
print join("  ", @{$_}), "\n" for @outtie;

<golf> 
@_=(['a'..'z'])x26;
print"@$_\n"for@_;

note to chipmunk Yes, that's true, but note the <golf> tags... :)

    @_=(['a'..'z'])x26;
    Careful! That creates @_ as a list of 26 references to the same array. If you change an element in any one of the rows, you'll have changed that element in every row.
    push @outtie, [ @alpha ] for @alpha;
    This snippet from your expanded solution is the preferred way to avoid this problem.
