NAME
Tie::AliasHash - Hash with aliases key (multiple keys, one value)
SYNOPSIS
use Tie::AliasHash;
tie %hash, 'Tie::AliasHash';
$hash{ 'foo', 'bar' } = 'baz';
print $hash{foo}; # prints 'baz'
print $hash{bar}; # prints 'baz' too
$hash{bar} = 'zab'; # $hash{foo} is changed too
print $hash{foo}; # prints 'zab'
DESCRIPTION
Tie::AliasHash creates hashes that can have multiple keys for a single
value. This means that some keys are just 'aliases' for other keys.
The example shown in the synopsys above creates a key 'foo' and an alias
key 'bar'. The two keys share the same value, so that fetching either of
them will always return the same value, and storing a value in one of
them will change both.
