AAP is quite an interesting project, but unfortunately it doesn’t really go far enough.  For example, pointers are integers, code and data pointers have the same representation, the memory is byte addressable, code addresses can be materialised from integers, and so it doesn’t come very close to representing the weird things that you see in non-mainstream processors.
