How about just casting in the ITD?
((ConstrainingClass)this)..someConstrainingClassMethod();
I have thought about adding the ability to ITD directly onto type
variables, just haven't gotten around to exploring the finer details
yet:
public abstract aspect GenericAspect<Type extends ConstrainingClass> {
public void Type.someMethod() {
this.someConstrainingClassMethod();
}
}
