diff Include/objimpl.h @ 37728:588f97b24bf9 legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
frame_traverse(): Use the standard Py_VISIT macro. Py_VISIT: cast the `op` argument to PyObject* when calling `visit()`. Else the caller has to pay too much attention to this silly detail (e.g., frame_traverse needs to traverse `struct _frame *` and `PyCodeObject *` pointers too).
