For '<', '<=', '>' and '>=' I agree, but for '==' and '!=' I very much
disagree since they have an obvious easy-to-define meaning (i.e.
that objects of incompatible types are different). As I understand it
'<' etc can produce exceptions these days, does anyone know if '=='
and '!=' can (in the absence of any weird non-standard user-defined
classes overriding __cmp__ or somesuch)?
