Does anyone else use relative submodules?

["Soni \"They/Them\" L." <fakedme@...>]

Lua has this neat syntax for relative submodules: require(.....".foo").
Wondering if anyone else uses these?

e.g.

-- file foo.lua
local bar = require(.....".bar")
local M = {bar = bar}
return M

-- file foo/bar.lua
local M = {}
return M
