Other program languages have limits in their standards. For example: Values for #line in the C preprocessor: "If lineno is 0 or greater than 32767 (until C99) 2147483647 (since C99), the behavior is undefined." https://en.cppreference.com/w/c/preprocessor/line Similar for C++'s preprocessor (but for C++11) https://en.cppreference.com/w/cpp/preprocessor/line (These days I maintain GCC's location-tracking code, and we have a number of implementation-specific limits and heuristics for packing file/line/column data into a 32-bit type; see https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libcpp/include/line-map.h and in particular LINE_MAP_MAX_LOCATION_WITH_COLS, LINE_MAP_MAX_LOCATION, LINE_MAP_MAX_COLUMN_NUMBER, etc) Hope this is constructive Dave _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/7N3CF4MDOBSPKANRZJSZOY6JVAGOCHXF/ Code of Conduct: http://python.org/psf/codeofconduct/
