\o/ toclose! (I'll echo that a more Luaish syntax would be preferred
but I trust the Author's judgement on this.)

I thought I'd also share that another useful local qualifier would be
<static>. This would be a variable scoped as normal but is initialized
once when the surrounding closure is created. i.e.:

function foo(...)
  local <static> cache = {}
end

is syntactic sugar for:

do
  local cache = {}
  function foo(...)
  end
end
