Your ints module is nice, and I think if it were in the standard library 
I'd be a lot less motivated to push PEP 284.  But, the objection to it 
will be that it only creates closed intervals, where other Python 
objects create half-open ones and it would be nice to have a syntax that 
would allow any combination of open and closed interval endpoints.
