In the handful of languages I have worked with so far, it's the other way 'round: you un-optimize debug mode in. CPython itself is a good example: when configuring, you must add --with-pydebug in order to get all the extra checks added (which is great when adding new features), but that option isn't used when making production CPythons; yet Python the language is just the opposite: debug mode is on /by default/, and to turn it off you have to specify -O: $ ./python -c "print(__debug__)" True $ ./python -O -c "print(__debug__)" False - -- ~Ethan~ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAEBAgAGBQJUZmjlAAoJENZ7D1rrH75N3wMP/j9AowuuEvW9khTFX512QUHn VGwEqkIu4FDFRA8T+qzwqhL7st5GGsnXaPvaWCLmPGbtt1qrVxJ1M6LLkuSWI8Fj /hGe5rcEPP88/tMA5zy/pmg6jDgl96hojCnDmmS6meIQijVRpxMUGQ/4+N1oKI5d JYKOlhFStk0N5O6gyZ3Yc6UDY+I9kLVPZsIgH0bXx5IkvwQUi1aNboADehDgSbM5 XDCuZvfNsauKyJZL52NkKu6qLSY/CHDx4kaWdP/i75gZPeVJirjEUkcLYSK6iE19 DpkyeR5wetH1yppH27yyfZPCKHnaYD8O/rykRrQLaIYefKb7XhxGWXa4C17w+AQP 3+hjONiPBsXe2FZZNTskKufI88oXbFwTyI3GseeWTIbS+V9TIwGTjZA+V9jc6EvL T6T9PRGwOzfPolcLZ43x3ea8uCzLhxe0BILEfdmv6XPoPl9sJ5wHhbxg0oblo8GL GNkfOFw0ncxplyobU0RXhvsKCUg6EpAukWgIcX5IhHfnesoS1BpSMtZubAbY4GVI AHzL34KpYhOIDo3Ws26dCtHz5ocJSnDlHv2lxv+iEEZV+4lShFEreqfCLK0hcJTP QMFoI401Dy3bLd3wJX9mYQA+nMGhNtRK+4uYwGSbAinOGDKVuqrmNM7wCaF9lr/I aC+wno9PzNxkDNy2nUpY =gJhZ -----END PGP SIGNATURE----- -- https://mail.python.org/mailman/listinfo/python-list
