I guess I could compile the string that Lua Pickle produces.
I was considering putting the unpickling code in the pickled data so
just doing a dostring would result in the unpickled datastructure.
See has advantages(like pickle version independence) but it would increase
the stored pickle size. Is that what you were thinking of?

Yes, unfortunately I can't rely on all functions being defined that way.
I guess I could have pickle only raise an error for non-dostring defined
functions, but it would be nice if it worked in all cases.

Great - I'll give that a try.
