Could someone explain to me what causes this behaviour ?

#!/usr/bin/perl -w

use strict;

my @subs = ("_iata_city");


foreach my $sub(@subs) {
    $sub =~ s/^_//g;
    print $sub;;
}
foreach my $sub(qw/_iata_city/) {
    $sub =~ s/^_//g;
    print $sub;;    
}

1) First loop = iata_city
2) Second loop = Modification of a read-only value attempted
I am assuming it has something to do with the _ in the qw// but am not sure why ?
