Equality comparisons (==, !=) will compare for object identity (is, is not) by default. I guess that you're talking about comparisons between different datatypes... but you didn't explicit that in your blog. Am I right?
No. The default comparison always raises an exception. Of course, most types have a comparison that does the right thing for objects of the same type -- but they still raise an exception when compared (for ordering) to objects of different types (except subtypes or related types).
