Funny, I was just at the point of writing exactly that sort of thing,
though based on my own, more Perl-oriented pack/unpack code.
One quick remark after skimming the code. In pickle() I see this:
> elseif t == "string" then

and further down this:
> elseif t == "function" then

If I understand the documentation for Roberto's struct library
correctly, "BBc0" won't allow strings or functions longer than 255
bytes. Shouldn't the pack code be "BHc0" (max. 65535) or even "BLc0"?
(Of course, unpickle() would have to change accordingly.)
Or am I missing the obvious?
