Possible issue with member mixins

[disarray2077]

The code below doesn't compile, but looks like it should since it works if you use this. to call the Test2 mixin inside Test3 mixin.

class TestMixin
{
	public void Test1()
	{

	}

	public mixin Test2()
	{
		Test1();
	}

	public mixin Test3()
	{
		Test2!();
	}
}

public static void Main() 
{
	TestMixin test = scope .();
	test.Test1(); // Ok
	test.Test2!(); // Ok
	test.Test3!(); // Failed to inject mixin.
}
