Mixin template functions are ignored in struct

[tcak via Digitalmars-d-learn]

I have written a struct and a mixin template, and that mixin 
template is mixed into that struct as follows.

private mixin template TestCommonMethods(){
	public bool apply( int d, int e ){
		return false;
	}
}

public struct Test{
	public mixin TestCommonMethods;

	public bool apply( char c ){
		return true;
	}
}

void main(){
	Test t;
	t.apply( 5, 3 );
}

---

For the line "t.apply( 5, 3 );", error is given saying that 
"function test.apply(char c) is not callable".

---

For better testing, I added another function to template as 
"public bool blah(){}", and called it in main, and it works. So, 
thus this mean overloading is not supported with mixin templates?
