Actually, neither Robert Bradshaw or I made any changes to the __cmp__ - related code in SageX versus Pyrex, so they should behave identically unless something was done in Pyrex recently. And even then, Robert just told me that "No, I haven't changed anything. We do have special _cmp_c_impl, etc. in element.pyx that calls canonical_coercion for you though. BTW, I got Pyrex 0.9.5.1a successfully merged into SageX!" So -- soon pyrex and sagex should be merged again.
