Comment (by Ramiro Morales):
I'm afraid catching `TypeError` around the view callable execution is a
too coarse net to have. what if the view (be it either a traditional
function-based view, or a correctly invoked class based view via it's
`.as_view()` method, etc.) result in a legitimate `TypeError`? Wouldn't
the useful traceback that cold help the developer diagnose the issue be
replaced by the new one that reports `"Check if as_view() method called
properly"`?
In the end there a needs to be placed between handholding a developer
which face this kind of problems, and the expectation of them reading the
relevan documentation, i.e.
https://docs.djangoproject.com/en/dev/topics/class-based-views/#simple-
usage-in-your-urlconf
https://docs.djangoproject.com/en/dev/topics/class-based-views/intro
/#using-class-based-views
I'm ok with trying to be more helpful but not at the expense of reducing
the usefulness of normal Python debugging techniques.
