This looks like a fail to me:
package.loading = function () return true end; dofile("mod.lua")

The question is to know whether a *module* was called by require,
not a stand-alone code that expects regular arguments to work.
Why anyone would call that with 'require'?

What Dirk suggested since the beginning: check whether the first
argument is the module name.
