Re: Can I get the return values NOT adjusted to zero?

the standard way to do this is:

2

> =two()
2

Is that too "special" ?

probably can't automatically prepend an equal, as this breaks function definitions.

Should I just take their input, and put a "return( " before it and a ")"
after it? This seems a little hackish... is it the best way? What I
really want is the _expression_ to not have its return stack discarded.

I'll have to implement __tostring for tables, I guess.
