AFAICT there should be a separate docstring for AbstractVector, right? Also, ::Integer would be useful since there's no longer any indication of the expected type in the signature.

I'd rather keep dim or use region, which are the two terms that appear to be common in similar functions.

This is what the method uses. They used to be out of sync. However, since we have reducedim, it is probably better to use dim here as well. I'll update.


Cumulative operation `op` on `A` along the axis `axis`, storing the result in `B`.

LGTM apart from the singular/plural issue with "dimensions" in several places.

singular/plural issue with "dimensions" in several places.

Should be fixed now.

Fix bug in accumulate when initial value is provided since the implementation
doesn't support multidimentional arrays.

Move the accumulate methods with initial values to the end
