Not sure if I’d call that the ‘best’, but it’s certainly one solution.

I’d probably prefer to use something like :

   function import(name)
       local mod = require(name)
       return function(t)
           for k,v in pairs(t) do
               t[k] = mod[v]
           end
           return unpack(t)
       end
   end

Import locals:

   local C,V = import "lpeg" { "C", "V" }

Import globals:

   C,V = import "lpeg" { "C", "V" }

Note this modifies the table passed in, but could just as easily return a 
new table.
