Just looked at the source to see how this message is generated.  Thought it
would be in __future__.py, but it isn't.  There's some hacky code in
future.c that says:

        } else if (strcmp(feature, "braces") == 0) {
            PyErr_SetString(PyExc_SyntaxError,
                            "not a chance");
            PyErr_SyntaxLocation(filename, s->lineno);
            return 0;
        } else {

No interesting comments there or anything.  I think this was just a cute
addition, and not really something with a "history". :)
