I've also tried __traits and other stuff. I have access to the 
interface and I've tried hard coding the name and other stuff... 
Using them on simple example case works so it is an issue with 
the code, here is the full code:

just mixin the templates to use use them, e.g.,



interface A(T)
{
	final string foo() { return ""; }
	mixin tPropertyBuilder!(0, T);
	alias Value this;
}


class B(T) : A!T
{
	@property T Value() { return _value; }
	mixin tPropertyImplementer!(0, T); // implements foo, causes 
compile time error. should not implement final members.
}
