Hi, the idea here is just to add the __larrow__ and __rarrow__ operators for <- and ->.
E.g. of use on dicts : >>> d1 = {'a':1, 'b':1 } >>> d2 = {'a':2 } >>> d3 = d1 -> d2 >>> d3 {'a':1, 'b':1 } >>> d1 = {'a':1, 'b':1 } >>> d2 = {'a':2 } >>> d3 = d1 <- d2 >>> d3 {'a':2, 'b':1 } Or on bools as Modus Ponens [1] Or your idea/imagination here :-) Regards, --francis [1] https://en.wikipedia.org/wiki/Modus_ponens _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
