I don't need a fail-proof method. I need a method that works for a
one-file module of which I know the name by which it will be required.

It does not do what I want.

$ lua
Lua 5.3.4  Copyright (C) 1994-2017 Lua.org, PUC-Rio
> dofile"lmodules/mod.lua"
package

I.e. "doflile" is treated just like "require'.

I want "require" to return and all other ways of running the file to continue.
