Re: [aspectj-users] array pointcuts?

["Wes Isberg" <wes@xxxxxxxxxxxxxx>]

Hi Mark -

Most useful when asking for a new feature is a compelling 
use-case.  It's safe to say at this point that many features 
have been considered and rejected, typically not because they 
couldn't be implemented, but because the increased power 
wasn't worth the complexity and confusion given the limited 
value of the use-case.

One test (that this case may or may not pass) is that 
the feature should behave the same after minor edits that
programmers would take as being identical, so the aspect
doesn't change accidentally.
