I'd love to see that. In fact, I work with a custom C library now that
does something interesting, which is a deep copy with internally
consistent references (or maybe that's what you meant by "deep with
refs"?). In other words, if you setup this table:

oldtbl["a"] = {"somedata"};
oldtbl["b"] = oldtbl["a"];

you can copy it to newtbl such that newtbl["a"] would be a new copy of
the "somedata" table, and newtbl["b"] would be a reference to the
*new* table copy in newtbl["a"].

I know, wishful thinking, but anyhow...
