I've thought a bit about this; I reckon it's possible to do this for
"self" attributes inside class methods.  It gets harder in the
presence of inheritance, but I think it could be done.  After all, in
class methods you know that the type of "self" is...

Doing it for external accesses would be harder, methinks.  Another
idea I might play with in some of that copious free time...
