Yes I see that now, however I thought that the concept of "2 locals  
of the same name" is a bit strange.

For example, at global scope:

a = 22

a = 44

This does not create 2 copies of a - how can it, as "a" is held in  
one place: _G ['a']?

Thus I assumed that putting "local x" in twice would simply  
"reconfirm" that x is a locally declared variable inside its function.

Thanks for the quick response.
