Um, no.
%module is a hash
$module{somekey} locates a value in the hash %module
$module is a separate scalar.
Try this:
use strict;
use warnings;
my %module = ('cygwin' => 'Cygwin');
my $module = 'Lunar';
print "hash el: " . $module{'cygwin'} . "\n";
print "scalar: " . $module . "\n";
I will admit might be confusing to use a scalar $module and a hash %module, but it is
not an error.
