Correct, and now I understand also my misunderstanding with my first 
variant - I didn't realized that it is interpreted as return type. But 
when I tried

after(Object x) : execution((@Alien *) Passenger+.new(..)) && this(x)

it compiles (I want to hit all Passenger subclasses with an @Alien 
annotation). It is similar to the first example (that with the syntax 
error) but does not work as I expected. Now, if I understand you correct 
the (@Alien *) here is standing for the return type -- but then it 
shouldn't compile (a constructor has no return type, as you mentioned 
correctly)?!?
