We can write a function which have parmeterized return type like this:

def <T> getSingleTone(Class<T> type){
	return type.createSingleTone() as T
}

But we can't write a create function like this:

def <T> create type.createInstance as T createSingleTone(Class<T> type){
}

I couldn't figure out why there is such restriction on create function.
