So I have a challenge for you all: A table copy script in less than 270
chars
239 bytes. Stole some of your tricks. Not extensively tested but seems
to work ...

Uhh it doesn't handle replacing _G.pairs with nil...
That is true. Of course you could add a local one-letter alias for `pairs` at the cost of 4 extra characters. While you are at it, replace `pairs(a)` with `next,a ` which saves another byte. So it's about 242 bytes now.
Also I don't like that wrapper function nonsense...
(table.copy.shallow(t,1) etc... bugs and obfuscation...)
There are no wrapper functions. I just used one function to implement the other via an extra boolean parameter (which you suggested in your OP, btw.). Both versions can't handle extra arguments correctly (my `shallow`, your `deep`), and both are properly obfuscated. I optimized specifically for code size which I thought was the challenge (obviously I misunderstood) ... Of course, I wouldn't write nor use either version under normal circumstances.
