I think you are picking nits. Sure the byte code could compile -42 into a byte code for 42 and a negation. Just as it could compile 42 into byte code for adding 32, 8 and 2. The point is, that the reverse isn't true. It couldn't compile [5, 8, 13] into a LOAD_CONST. -- Antoon Pardon -- https://mail.python.org/mailman/listinfo/python-list
