Re: Why should not toclose be the default?

You would need a different "keyword" to mark the intent to "leak" the resource. Hypothetical current-Lua code:

function sandbox.open(filename)

  assert(checkpath(filename))

  local f = assert(io.open(filename))

  -- some other processing on f

  return f

end
