Yesterday I posted a question about getting data from an array and I was given an excellent answer by broquaint. I'm trying to get particular data from an array and he suggested using a hash, which works perfectly because now I can get other data from the hash when I need. However, I came across an unexpected result.

my %hash = map { chomp; split /,/ } <DATA>;
print $hash{1006},$/;

__DATA__
1001,choochoo
1002,candycane
1003,sockpuppet
1004,choochoo
1005,candycane
1006,sockpuppet6
1007,foo
1008,bar

Works great! However, some of the data is actually set up like this:
__DATA__
0001,choochoo
0002,candycane
0003,sockpuppet
0109,choochoo

[download]
This doesn't work with references that start with '0'. In fact the '0109' even gives the 'illegal octal digit' warning.

Can anyone shed some light on this? Possible workarounds? I can't change the way I receive the data. The "000's" are what I get.
