I don't think you can do that anymore. In the old days you could use %x
to give you the "upvalue" of x, which was the outer scope value. I
believe upvalue syntax has been removed, which is probably a good thing.
You can't get the outer scope value in C/C++ when you have a clash, and
neither can you in Lua. Unless you use the debug interface (don't!) I
don't think you can get the value without nasty coding. Refactor your
algorithm or copy the value.

Regards,
Nick

    I remember of a discussion some times ago, in this list, about the use
of this, well... I now know the result :-). I can't use anymore :-(.

                                    Thanx.
