It doesn't need to know. So long as the compiler can guarantee that its code will produce correct results in the case that a and b *do* both point to the same array, that's enough. In other words, when producing code for ptr_compare, the compiler is allowed to *assume* that a and b point into the same array, and act accordingly. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10044> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
