Documentation clearly states that the 'L' is a 4 byte integer.

Is this a bug? I'm I missing something? By default pack uses native size, not standard size. On a 64-bit machine:

As the OP points out, the documentation says that the "Standard Size" is 4 bytes (http://docs.python.org/library/struct.html). While "Standard Size" doesn't appear to be defined in the documentation, and the start of the previous section (7.3.2.1. Byte Order, Size, and Alignment) clearly states that C types are represented in native format by default, the documentation could probably do with some clarification.
