Not as readable as a.append(4), which works today and doesn't require the user to memorise the special case that <<= works on lists but (presumably) << doesn't. Or perhaps it would. What would a bare << mean for lists? b = a << 4 could mean the same as b = a + [4] but we already have a spelling for that, do we really need another one? -- 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/
