Fellow monks,

I know this should be simple, but I am tired and am not seeing the problem. Here's my code:

use strict;
use warnings;
use Data::Dumper;

my @trainset = ();
while (my $pattern = <DATA>) {
 chomp $pattern;
 next if ($pattern =~ /#/);
 my ($inputs,$outputs) = split(/=>/,$pattern);
 my @inputs = split(/,/,$inputs);
 my @outputs = split(/,/,$outputs);
 $trainset[scalar(@trainset)] = \@inputs;
 $trainset[scalar(@trainset)] = \@outputs;
}
print Dumper(\@trainset);

my @set = (
           [0,0] => [0],
           [0,1] => [1],
          );
print Dumper(\@set);

__DATA__
0,0=>0
0,1=>1
#not used

The two arrays should be the same, but the output of Data::Dumper on the two arrays is different (when read in from a handle, the values in the arrays are scalars instead of numbers) and I think it's causing me problems further on. What am I doing wrong?

Thanks a bundle.
