Uh oh, maybe unless you commonly use _ as a marker for "dummy variable
to assign to", as in:
  for _, v in ipairs(tab) do --[[ something ]]-- end
or:
  local x, _, z = fooBar()
- then I wouldn't advise _ for i18n as you might get some some issues
because of variable scoping...

Actually, I thought this use of _ (as "dummy") is common and suggested
by PIL, but now after what you wrote, I'm starting to lose my
certainity... do I regularly follow some non-standard practice?
