Indeed, you're quite right. I've corrected the description here: http://codereview.appspot.com/186247/diff2/7005:9001/10001 > Now what's more interesting is whether or not U-S and Cython could > play off one another -- take a Python program, run it with some > "generic input data" under Unladen and record info about which > functions are hot, and what types they tend to take, then let > Cython/gcc -O3 have a go at these, and lather, rinse, repeat ...

Someone approached me about possibly reusing the profile data for a feedback-enhanced code coverage tool, which has interesting potential, too. I've added a note about this under the "Future Work" section: http://codereview.appspot.com/186247/diff2/9001:10002/9003 Thanks, Collin Winter _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
