+Like [`getindex`](@ref), but returns a lightweight array that lazily references
+(or is effectively a _view_ into) the parent array `A` at the given index or indices
+`inds` instead of eagerly extracting elements or constructing a copied subset.
+Calling [`getindex`](@ref) or [`setindex!`](@ref) on the returned value
+(often a [`SubArray`](@ref)) computes the indices to access or modify the
+parent array on the fly (without checking bounds a second time).
+
+Some immutable parent arrays (like ranges) may choose to simply
+recompute a new array in some circumstances instead of returning
+a `SubArray` if doing so is efficient and provides compatible semantics.
