I’m generating a module from a macro, like this:

defmodule WhereTheMacroIs do

defstruct [:same_for_all]

defmacro generate(name) do
  quote do
    defmodule unquote(name) do
      def simplified_example(%WhereTheMacroIs{} = msg), do: msg.same_for_all
    end
  end
end

end

defmodule WhereIUseIt do
  require WhereTheMacroIs
  WhereTheMacroIs.generate(SomeOtherName)

  def test, do: SomeOtherName.simplified_example(%WhereTheMacroIs{same_for_all: 42})
end

The problem I get is that the struct %WhereTheMacroIs{} will be name-expanded to %WhereIUseIt.WhereTheMacroIs{} when expanding macro WhereTheMacroIs.generate/1 - which is not what I want. I want all generated modules to use the same struct internally.

I googled for a while but I was unable to find a way to suppress this extension of the struct name.

This seems to happen even if an alias is used or not.

I’m using elixir 1.6.
