You know, Guido might as well give in now on the Macro issue. If he
doesn't come up with something himself, apparently we'll just hack
bytecode. I'm not sure that's a gain. (To be fair, I can see some
arguments that it is, so that "I'm not sure" isn't a
passive-aggressive/sarcastic snipe like most people use it in this
context; I mean it literally.)

(I expect if we ever do see them, this will be the basic argument used. I
guess you could call it Historic Inevitably. :-) )

I'm not just basing it on this one thing, I'm basing this on all the
bytecode hacks I've seen.
