[aspectc-user] weaving twice

[Olaf Spinczyk]

Hi Francisco,

I think this problem is related to bug #349 (member function called
"aspectof" in normal class causes parser crash). The problem is that
after the first weaving the aspect is transformed into a class that
contains a member function called aspectof. I will look into it.

Best regards,

Olaf
