SizeOf?

[Tom Allen]

I want to know how much space a hash is using.
The hash hashes straight scalar values as well as anonymous lists.
If I have a reference to the object ($obj), how can I
print "Object is using ".amount_of_RAM_used_by($obj)." bytes of RAM.\n";

Help!  I've searched google, the Oreilly cd bookshelf, and FAQ upon FAQ!
