These are unrelated parts. The scope of the variable (whether it is
local or global) matters when getting the variable itself, be it
`string` or `str`. *


[1] In the latter case, before even looking for the metatable. In
fact, lua doesn't call gemetatable() per se, but actually uses that
instruction `SELF` Tim mentioned earlier, which then internally looks
for the metatable.
