There is no pattern matching/regexp happening here.  The wild matching 
introduced in 8.1 just means that the identifier that you look up may be 
at any level, under some namespace or class.

Unless I am missing something, I believe that 'b ::abort' should do what 
you want, and the current behavior is simply buggy.
