Re "I think I read it somewhere". The use of _ for unused/throwaway
variables is definitely a convention in Lua. Maybe you read this in
Roberto's Programming in Lua? "Usually, I reserved the identifier _ (a
single underscore) for dummy variables" (page 5 in the 3rd edition). But
you may have read it in the wiki's style guide or a bunch of other places.

If I had to guess, the original tendency may have started with PiL, but
maybe people who have been in the community longer would know better.
