Yes, I forgot about the extra "*" for the (invalid) return type that was 
in the expression. Need to get my glasses checked, I guess ;)

I've made mistakes like this occasionally in my own PC definitions 
(PCDs). The PCD language is very "dense" and requires careful inspection 
of any PC. Given a lot of recent discussion in the bloggosphere about 
"humane interfaces" (e.g., 
http://www.martinfowler.com/bliki/HumaneInterface.html), it would be 
interesting to consider a more verbose & humane PC language for AspectJ 
that could be used with the existing language. When you consider that a 
typical PCD, like most code, is written once and potential read many 
times, I would certainly use a more verbose language if it were available.

For example, Perl has more human-readable equivalents to its many 
cryptic "$..." variables. What if AspectJ's PC language had special 
symbols like the following:

$any_return       => "*" used for the return type
$any_arg           => "*" for any single method argument
$any_arglist       => ".."

etc.

Just a thought...
