Hello All...

I'm having a problem generating hash keys using a sub. I'm pretty sure that this is a syntactic error and while I could easily "do it another way" I'm just curious as to why this occurs....

Let's set it all up:

use Digest::MD5 qw(md5_hex);
use strict; 
use warnings;

my $secret = "applepie";

[download]

Here's the sub function:

sub get_md5 
{
 md5_hex("$secret" . "$_")
};

[download]

This works great...

my @array          = qw(foo bar baz);
my %md5_other_hash = (map {&get_md5, $_ } @array);

[download]

Not this though:

my %md5_hash       = ( &get_md5('foo')  => "foo",
                       &get_md5('bar')  => "bar",
                       &get_md5('bar')  => "baz",
);

But Why?


Whereas, here we have no problem...

print &get_md5('foo');

[download]

Anyone care to help me understand what's going on here? I intuitively think it should be fine.... which is why I ask...

Many thanks in advance,

Cheers

SM
