 as a convenience for dispatch; it's a boolean that represents whether the index types support
 fast linear indexing. More on that later.
 
-If in our example above `A` is a `Array{Float64, 3}`, our `S1` case above would be a `SubArray{Int64,2,Array{Int64,3},Tuple{Colon,Int64,UnitRange{Int64}},false}`.

 Note in particular the tuple parameter, which stores the types of the indices used to create
 `S1`.  Likewise,
