Description
The .from_buffer[_copy] methods of ctypes types only accept an array.array argument. Other implementations such as cpython, pypy also accept bytes, bytearray, mmap, memoryview etc.
The struct and re module accept a wider variety of buffer-like objects. Strangely, re accepts mmap objects, but stuct does not.

Research direction
Start at the ctypes .from_buffer and .from_buffer_copy entry points and compare their accepted inputs with array.array, bytes, bytearray, mmap, and memoryview; inspect the existing struct and re behavior noted in the issue. Done means both methods accept the intended buffer-like objects consistently.
