Description

In the single use case I have for AxisArrays right now, it would be very convenient if the default indexing of an AxisArray used the values of the indices instead of the indices of the indices. E.g. if I do

x = AxisArray(Axis{:x}(-3:3))
x[[-2,1]]

it would be handy if it returned the second and fifth element of the AxisVector. You can always refer to the indices of the indices by using the Axis type. Could this work?

Research direction

Start by reproducing the Julia example with AxisArray, Axis{:x}, and value-based indexing, then review the existing AxisArray and Axis indexing behavior. Done means the example returns the elements selected by axis values while index-based access remains available through the Axis type, with the intended behavior covered by tests.

Written by the indexing model from the issue text.
