I do suspect though that both the hashing and 6-bit weight examples are just extremely rare in the corpus. It wasn't confused about loops, or hashing generally, but just didn't do as well as antirez would have liked. The description of the 6-bit to "why don't I just cast this to 8-bits" thing is definitely a problem. And worse, it's a problem a more junior engineer might not understand. But I suspect that a model trained on a corpus with lots more bit manipulation would have been fine, as it wasn't complex.

Clearly we just need a fine tuned one :).
