 Variant of [`sort!`](@ref) that returns a sorted copy of `v` leaving `v` itself unmodified.
 
-Returns something [`similar`](@ref) to `v` when `v` is an `AbstractArray` and uses
-[`collect`](@ref) to support arbitrary non-`AbstractArray` iterables.
-
-!!! compat "Julia 1.10"
-    `sort` of arbitrary iterables requires at least Julia 1.10.
