[aspectc-user] Weaving in Macros

Ah, that was it indeed. Thanks.

I did try it with wildcards though... I just tested it again and my 
problem was that %sc_module does /not/ match the classes while 
%::sc_module does. The documentation states that

"In such a search pattern the special character "%" is interpreted as a 
wildcard for names or parts of a signature. The special character 
sequence "..." matches any number of parameters in a function signature 
or any number of scopes in a qualified name. A match expression is a 
quoted string."

Especially the plural ("names" or "parts" of a signature) made me think 
that the % wildcard could be used for more than a single name. Is there 
a definition somewhere what exactly is matched by % and what isn't and 
what the delta is to the ... wildcard? That'd be very helpful, thank you 
in advance.

Best regards
