> Nice to have a set type ;-)
Yes, it is!
> Is there an efficient s1==s2 test?
Yes. It's spelled s1 == s2, BTW (likewise s1 != s2).
> Or should one take that for granted?
No, it takes effort to do that efficiently. Indeed, "rich comparisons" were
implemented a few releases back in part so that objects *could* do something
extra-efficient for specific comparison operations, and the implementation
of dict comparison was changed soon after to exploit that for "==" and "!=".

You can if you're crazy <wink>.
