AA implementation is provided by 
https://github.com/dlang/druntime/blob/master/src/rt/aaA.d, and 
you can either try reimplementing key logic in Python (more work 
but cleaner impl) or just call relevant functions via gdb python 
api and parse results. It should actually be possible to call 
functions like __aaGetX even with release build of druntime, you 
just to do a manual cast to the correct function type from a raw 
pointer.
