Actually, writing out alts initialisation by hand has always seemed
clumsy to me.

void
newalt(Alt *ap, ChanOp op, Channel *c, void *v)
{
	ap->op = op;
	ap->c = c;
	ap->v = v;
}

	Alts alts[3], *ap = alts;

	newalt(ap++, CHANRCV, done, nil);
	newalt(ap++, CHANSND, c, val);
	newalt(ap,   CHANEND, nil, nil);

seems a bit more obvious and only requires one additional line per
channel.
