Sure, the *object* of a particular head of lettuce may be unique, but
we're not tracking lettuce heads -- we're tracking the *idea* of a
lettuce head in a capitalist system, an ownership relation.
Besides, in the worst case, these damn object ID's aren't very
compressible. Best representation of a unique head of lettuce I can
think of is... that very head of lettuce.
Of course, an accumulator is much easier to write, since the Pauli
Exclusion Principle guarantees that adding a head of lettuce to a bin is
an _atomic operation_
:-)
