Perhaps I misunderstand you but I think that's not the
case.
local i,j,k,dmz,x,y,z=1,2,3,0,4,5,6
local dmz=7
The two definitions of dmz have different scopes, with the
second one shadowing the first in the area of overlap.
Incidentally, if I remember correctly the priority of
same-named variables in a local statement or parameter list:
local a, a, a = "left", "middle", "right"; print(a)
right
is undefined by the reference manual, although it is
predictable in practice.
Having two parameters with the same name is almost 100% an
error
True, though perhaps not in automatically generated code.
