right.

"local" to a lexically-scoped language means "local to the code
specified in this piece of text".  a C function is at another lexical
context, so by definition it shouldn't be able to meddle with Lua
local variables.

of course, there are ways to do it, either via the debug API, or
hacking the interpreter itself.  But neither of those are meant to be
used as "normal execution", and that's by design, not because of
oversight.
