That said, Larry's original proposal relates to sys, a built-in module written in C (in CPython of course). In that case the solution is not quite the same, since module initialization interacts with sys.modules differently. [1][2] Accommodating the original request would require more work, whether to muck with the import C-API or making sys an instance of another type, as someone suggested.
sys is already special cased so heavily in the interpreter initialization, making it a little more special really wouldn't bother me much :)
As far as customising other extension modules goes, the same "replace yourself in sys.modules" trick should still work, you'd just do it via the C API from your module init function.
Don't extension modules get added to sys.modules only after their init function returns? -eric
