Re: [aspectj-users] Defining a pointcut selecting no joinpoints.

[Wes Isberg <wes@xxxxxxxxxxxxxx>]

Sorry, just to be clear: the idiom is to declare a pointcut and
not define it (not to use a pointcut called "empty"):

   pointcut p();

There was a aspectj-dev thread on ~ undefined concrete pointcuts~
a while back, and it's in the sample code (and not the docs,
perhaps because there's not consensus that it's the right thing).

I personally object to it because it's so close to an abstract
pointcut that someone could easily leave out "abstract" and not
realize it.  It has the advantage that if this (imho) bug is
ever fixed, you'll get a compile-time error.
