if a module used to export a method, and a breaking change is made such that it doesn’t anymore, is there anyway to deprecate it? thanks.

Maybe:

```julia
julia> module Foo
           @deprecate exported() Foo.unexported()
           unexported() = println("Not exported")
       end
Foo

julia> using Foo

julia> exported()
