- Subject: Weak keyed tables with primitive keys

My google fu is failing me on this one.
Where can I find a definitive discussion of weak keyed tables and the
behavior of primitive data types as those weak keys? My tests say
that unique string keys are never collected, and while I can see a
justification for that I'd really like to know the relationship of
primitive types such as strings to the garbage collector. Do we have
to use tables or user data as keys in weak keyed tables in order for
them to be collected?
Many thanks in advance,
