two-way hashes

[raptor]

hi,

I tought about a posibility to access a HASH in way that the VALUES can also
be used like KEYS...i.e in perl6 I will say this :

%hash{key} = value;

I want to say also :

{value}hash% = key;

print {value}hash%;#will print the key for this value...

joking :")) but is this good... or I'm talking bullsh...s  again ..
Ofcource this mean that we can't have the same value in the HASH.
