In some module systems, certain modules utilize the import mechanism
to apply a special side-effect into the caller. A Perl style way of
import "strict" -- i.e. require "strict" : __import()
Here, *every* instance of "import 'strict'" would apply a side-effect
into its caller environment, unlike "require 'strict'" in Lua 5.1
which permits no side-effects after its first call.
