QOTW:  "A quick rule of thumb for Python: if your code looks ugly or
strained or awkward, it's probably also wrong." - John Machin

Then, should Python raise a warning when mutable default arguments are
used?

exceptions a function can raise:

Inner functions aren't attributes of the outer one:

Using class attributes as if they were "declarations" for corresponding
instance attributes is discouraged:

[ANNOUNCE] pygtkmvc-1.2.2 has been released

==
About pygtkmvc
==

pygtkmvc is a fully Python-based implementation of the
Model-View-Controller (MVC) and Observer patterns for the PyGTK2
toolkit.

MVC is a pattern that can be successfully used to design and
develop well structured GUI applications. The MVC pattern
basically helps in separating semantics and data of the
application, from their representation.

The Observer pattern helps to weaken dependencies among parts that
should be separated, but need to be connected each other.

pygtkmvc provides a powerful and still simple infrastructure to
help designing and implement GUI applications based on the MVC and
Observer patterns.

The framework has been designed to be:

* Essential and small, it does only what it was designed for.
* Not an external dependency for your application: it fits in
  80KB and can be released along with it.
* Easy to understand and to use; fully documented.
* Portable: straightly runs under many platforms.
