Those of us who post code snippets on Lua-L with officious "local"
statements in it, making it unrunnable in the standalone, must bear
at least part of the blame for that. Especially so if that code purports
to answer a newbie's question.

This could be a useful feature for one of the customizable REPL's
that people announce here from time to time (can't remember the
names, please put up your hands) but IMO does not belong in
"a sample host program called `lua`".
