Yes, but only countably infinite, so at least we can enumerate them all. Eventually :-) And aside from the tiny niggle that *** and higher order operators are syntax errors... Its not a bad example of the syntax, but it would be considerably more compelling a use-case if it were something less obscure and impractical. -- 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/
