Okay, so, I don't have a patch, but I have made a script to examine the 
situation. It seems the problem is a little more widespread than I had 
realized. I grepped through the python C source to find all the type 
objects, and then verified their existence. Just looking at 
Objects/*.c, there are 31 classes without appropriate bindings. 
Additionally, some aren't even valid identifier names. It seems like 
there's 4 categories here: iterators, descrobject stuffs, list 
comparison wrappers, and other. I'm not sure it's a good idea to add 
all these names to the builtins -- perhaps only the ones in the 'other' 
group?

For {Modules,Mac,PC,RISCOS,Python}/*.c, most seem like they could 
relatively straightforwardly be added to their module, but I haven't 
examined them too closely. Some likely ought to have constructors added 
(e.g. the dl.dl('file') could be equivalent to dl.open('file')).
