Since all operations increase the accumulator, I tried putting a guard (a <= x) in apply, but it doesn't actually help all that much (0.65s -> 0.43s).

0.65 -> 0.43 sounds pretty strong, isn't that a one-fourth speedup?

Edit: I was able to achieve a 30% speed improvement using this on my solution

It's not insignificant, sure, but I'd prefer 10x faster :D

Plus I'm not sure it's worth the loss of generality and readability. It is tempting to spend hours chasing this kind of optimization though!
