I'll put this in JIRA.

There are some problems with this approach:

We will work on trying to remove the need for the aspect to extend the Aspect base class. That
leave us with the only possibility of inspecting the class attribute to see if we have an aspect.
But this might not be sufficient since the @Aspect attribute is not mandatory, this means that we
have to parse all classes on the whole classpath, jars, dirs etc. and  inspect their fields or
method attributes in the search for an advice or pointcut attribute. This is doable but will be
very slow, but if this is important it is perhaps the only option. I agree on that it would be
very neat to have.
