That's a good point.  I'll add a SF entry to request these unit tests.

What you see as whimsical was actually done for compatibility reasons;
the new-style classes look more like built-in classes, whose repr is
<type 'int'> or perhaps <type 'module.C'>.  (It says 'type' if it's
pure C, 'class' if it was created by a Python class statement.)
