Julia: `parentindices` naming consistency

[tkoolen]

Now that indices has been renamed to axes, should parentindices also be renamed to parentaxes?

parentaxes does seem slightly awkward by the way, sounds like a financial charge to dissuade people from using LISP.

Can we just remove it entirely? Like parent, it has a pretense of being generic without actually being helpfully generic.

[mbauman]

Even so, in this case, I think indices _is_ correct. It's specifically in reference to the indices you used to subset the parent. It is not the axes of the parent, nor would I describe the indices in something like the bitmask in @view A[A .> 0] or the linear indexing diagonal in @view A[1:size(A,1)+1:end] as axes.

Why does being generic matter? Some kind of stable interface would be very useful. Is there a guarantee that the name of the indices field of SubArray (actually, should that be indices?) won't be changed between minor versions?

Triage is full of apathy on this matter.

[tkoolen]

Haha, fair enough.

But seriously, we did discuss it and @mbauman was convinced that the current name is right.
