[erlang-questions] data sharing is outside the semantics of Erlang, but it sure is useful

Interesting answer, but not an answer to my real question.  (Maybe I went
on for a paragraph too long.)

It seems that James is interested in data structure sharing IN THIS
PARTICULAR CASE because it gives him a kind of data compression.  Again,
if that's the goal, why is ordinary data compression *not* the answer
here?  If compression isn't the goal, what did I miss about the
(implicit) problem statement, to which sharing semantics in Erlang *is*
the answer?
