I'm not sure I follow this proposal. Could you explain a little please?

Given

    x = Symbol('x')

as the current approach, how would you modify that to work with your
proposal? If you could show how you'd write a wrapper function
AutoSymbol, so that

    x = AutoSymbol()

did the same as the above, that'd help me a lot.

Thanks,
Paul
