I agree that it expresses intent clearer than the range(...) construct. > for use in conjunction with C code. > I believe that reason is still valid. I'm not sure why "in conjunction with C code" makes any difference to the argument, now that the basic range loop produces the same code in Cython. Put another way, does its clarity merit a PEP to introduce this syntax into Python? If not, it's hard to justify in Cython given that it is a fully redundant addition to the language. - Robert _______________________________________________ cython-devel mailing list cython-devel@python.org https://mail.python.org/mailman/listinfo/cython-devel
