Who says that "slower" doesn't still remain within the realm of "fast", perhaps even with a capital F? I wouldn't assume that the language as is is totally devoid of features that already complicate compilation -- that would probably result in some kind of polish notation proto pascal… So it's all about tradeoffs, and the go designers just say that this isn't worth it, at least for the current time and the current Plan9-ish Thompson compiler. Whether this crosses over from the pragmatic to the dogmatic is up for discussion (cf. dynamic linking).
