I don't see that.  If a source line refers to some module you can get
instantly to the module's code.  But you can't tell where any given
class instance comes from.  That's one of the usual criticisms of OOP,
that the flow of control is obscured compared with pure procedural
programming.

Easy to fix.  Instead of sys.stdout.write(...) say

  from sys import stdout

from then on you can use stdout.write(...) instead of sys.stdout.write.
