I want an array of anonymous arrays, each with some data and a code ref. The coderef defaults to the identity function; return the scalar that was sent. (This gets overriden as needed.) 
use strict;
use Data::Dumper;
my %x = map { $_ => [$_, sub {shift;}]} qw(a b c);
print Dumper(\%x);

The result isn't what I expected: 
$VAR1 = {
          'a' => [
                   'a',
                   sub { "DUMMY" }
                 ],
          'b' => [
                   'b',
                   $VAR1->{'a'}[1]
                 ],
          'c' => [
                   'c',
                   $VAR1->{'a'}[1]
                 ]
        };

Why do "b" and "c" share the same coderef as "a"? I had expected each would get a reference to their own sub.... Confused...
