Query: Does not have any Perl information

The book has a lot of hand waving but no concrete information on Python where it matters. For example there is no comparison of it with Perl. In fact they never say how the two can work.Also the authors do not cover at all the Meta Object Protocol of Python or for example how it does virtual pointer-based interface inheritance. These are important concepts that a student of Python must know. Also missing is any information on the transmutation of objects under constraints.All in all, way too elementary.
