Howdy all,
The builtin types have __repr__ attributes that return something nice,
that looks like the syntax one would use to create that particular
instance.
The default __repr__ for custom classes show the fully-qualified class
name, and the memory address of the instance.

If my read of the extension source (Mac/Modules/file/_Filemodule.c) is
correct, the parameter sizes specified for data and resource file sizes
are UInt32 where they should be UInt64.
In both OS9 and OSX Carbon, the MacOS File Manager (Files.h) uses
UInt64 values for data and resource filesizes.

Of course, in __setstate__, there should be a tup = list(tup) as well -
sheer forgetfulness and a confusing name in one.
--
http://mail.python.org/mailman/listinfo/python-list
The reason the state of obj.A and obj.B aren't preserved is because
your __getstate__ and __setstate__ don't preserve them - they only save
obj.C, and you don't make a call to the parent class's respective
methods. Here's what I mean:
>>> import pickle
>>> class Child(Parent):
__slots__=[
It is clear that just using 'print' with variable names is relatively
uncontrollable. However, I thought that using a format string would
reign the problem in and give the desired output.
Must I resort to sys.stdout.write() to control output?
