Unfortunately if you alter the code to call save() twice, the second
time, it serialises:

-- global environment
b=b
x=x
a=3
PI=3.141592653589793
_VERSION="Lua 4.0 (beta)"

----END

I.E. it fails to serialise the same structure more than once.
Not good.

Also, it relies on being able to insert __visited__ into each table.
I personally don't want that, hence I'm writing my own, using
a set of elements etc.

Daniel
