As mentioned earlier in this thread, that is not possible in Python as syntactically `x ++ y` would be parsed as `x + (+y)` (the plus binary operator followed by the plus unary operator). > this is the concatenation operator in languages > like Haskell (for strings) and the majority of Scala cases.

"<>" is familiar to many people as "not equal" in various programming languages, including older versions of Python. I'm not entirely sure what connection "<>" has to append, it seems pretty arbitrary to me, although in fairness nearly all operators are arbitrary symbols if you go back far enough. -- Steve _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
