This wouldn't solve the NaN problem though:
>>> nd = ndarray([(1,2)], shape=[1], format='dd', flags=ND_WRITABLE)
>>> nd[0] = (float('nan'), float('nan'))
>>> m = memoryview(nd)
>>> m == nd
True
What's the policy on importing modules in the Object/* hierarchy? Can we
import _struct?
The current unpack_cmp() function for identical single native format codes
is very fast. The only thing that would be needed to make it general is
to replace
default: return -1;
with
default: return unpack_cmp_struct();
The code is already there in _testbuffer.c. _testbuffer.c itself has 100%
code coverage (including all error conditions with a special patch).
This means that all tests are already present in test_buffer.py.
