31     """Attribute tracker, used for e.g. Variable tracking.
32 
33     Monitors certain attribute types
34     and put them in appropriate lists in case of a match.
35 
36     Also passively tracks certain mutable collections
37     (dict, list) so that items added to them later
38     still get tracked. This is done by wrapping these
39     collections into an equivalent, tracking-aware object.
