But C extension modules sure can. See: https://stromberg.dnsalias.org/~strombrg/checking-early.html . It uses Fortran to make its point, but the same thing very much applies to C. BTW, if you're using C extension modules, the troublesome one doesn't necessarily have to be one you wrote. It could be a dependency created by someone else too. -- https://mail.python.org/mailman/listinfo/python-list
