Importing a non-dependency inside a registered package

General Usage

Julia version: 0.7 alpha

It seems that using a package in some file belonging to a registered package gives a LoadError if it is not explicitly listed as a dependency. Is there a way to work around that? I understand why it is useful when importing a package known at compile time, but in my case I want to import it in runtime. Specifically, I have some code that worked in v0.6, looking roughly like

module MyRegisteredModule

function load()
    push!(LOAD_PATH, "some_dir")
    eval(quote
        using MyDynamicModule
    end)
end

end

where some_dir contains a file MyDynamicModule.jl with the module definition.

Is there a way to make dynamic loading work in v0.7?
