I am not quite sure about the purpose of this example,
but let me proceed with some tentative comments.

According to the criterion I have given, the definition
of MyClass has only one line, and no native statements
are involved, so it should be judged as a pure pythonic
class (If the definition does contain some native statements,
this class would be equivalent to 'cdef class', and still
visible to python as of current situation).

That being said, the second line of statement can also be 
treated as a pure pythonic statement. 

What do you think?
