Every Lua beginner makes the same mistake: using local variables in
interactive mode of Lua standalone interpreter.
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.
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.
