And Pathlib's use of / is not division, nor do C++'s streams use bitshifting. But overloading the matmul operator would allow this feature to work without changing the syntax of the language, nor breaking existing code (since no built-in types implement __matmul__). -- https://mail.python.org/mailman/listinfo/python-list
