This turns on what you mean by "piece of code" and "executed". As the
manual says, function definitions, looping structures, do ... end
structures and separate files of Lua source code constitute chunks.
Chunks contain sequences of statements or chunks. The notion of
subchunk, i.e. one chunk contained in another, is the salient concept
to be grasped, IMHO. Chunks form an ordered tree (in the mathematical sense
of that phrase) with root the chunk consisting of the whole program.
The scope of a local variable is the part of the smallest chunk containing
its declaration which follows it.
