  What is the concern here?  So far, Lua has managed without a conherent
namespace for modules.  If Ravi is meant to run existing Lua code then you
pretty much *can't* enforce a new requirement.

You can have multiple namespaces covering the same objects in Lua. So along with

  pl = require "pl"

I could have

  pl = nop_require "general/penlight"

which return the same object. Presumably you bootstrap the second with 

  nop_require = require "nop_require"

I think the painful issue then is fighting over how the underlying loader handles "real" module names in the "loaded modules" table. There could be other landmines too, though.
