Way I see it, a character string `P` is a chunk if and only if the first
return value of


is not nil, otherwise `P` is garbage.  Whether it is just one statement
or a 5000-line program.  ("garbage" and "chunk" may differ by only one
character.) (It is `load(P)` in 5.2 but for the moment `loadstring`
still works.)
