Description

I'm curious why the API has this indexing syntax and why it's different from standard Julia array indexing.

julia> A = AxisArray(reshape(1:60, 12, 5), (.1:.1:1.2, .1:.1:.5));

julia>  A[Axis{:col}(2)] == A[:,2]
true

julia>  A[Axis{:col}(2)] === A[:,2]
false

Research direction

Start from the AxisArray indexing API and the Julia REPL examples in the issue. Compare Axis{:col}(2) with A[:,2] and determine why they are equal but not identical, as well as why the syntax differs from standard Julia indexing. Done means the documentation clearly explains these semantics and the relevant examples.

Written by the indexing model from the issue text.
