I'd expect it's (1). A more nuanced version might be: (5) As a rule, an Integer should probably be returned if the code is probably going to interact with other sage code, but if you have good (efficiency) reasons to prefer a python integer or if the primary function is to be compatible with other python code (such as "len" methods) then returning a python integer should be fine.
The reality is that the "python integer" type interwoven with the language and sage cannot avoid it. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
