And those who post code snippets on Lua-L _without_ "local" statements
in it must bear part of the blame for the proliferation of unnecessary
globals in a lot of Lua code out there.

I'm of the opinion that any presented code should be of the highest
possible quality, especially in this age of copy-and-paste
programming.

I would be appalled if somehow "don't use locals in examples because
it confuses REPL users" became a recommendation. To me that's an
anti-pattern.
