8.8 The @ Type Descriptor
The @ type descriptor is used for a pointer-to-non-static-member-data type. It is followed by type information for the class (or union), a comma, and type information for the member data.
The following C++ source:
typedef int A::*int_in_a;
generates the following stab:
Note that there is a conflict between this and type attributes (see String Field); both use type descriptor @. Fortunately, the @ type descriptor used in this C++ sense always will be followed by a digit, (, or -, and type attributes never start with those things.
