The pure Lua bit.numberlua library [1] provides compatibility
interfaces for both 'bit' and 'bit32', and a couple of my modules
(e.g. digest.crc32lua and compress.deflatelua) natively support all
three bit libraries, doing things like

  local bit, name = requireany('bit', 'bit32', 'bit.numberlua')
  -- sometimes with conditionals on module `name`
