I would like to ask about the possibility to add some improvements to ctypes in Python 2.5, although the feature freeze is now in effect. Hopefully former third-party libraries can have the freeze relaxed somewhat;-). Ok, former third-party libraries get a 1e-308 reprieve. :-) I think the general answer is to plan some way that you could make an external release to support the other communities like numpy. I don't know the details, but I believe Barry does this with email. This would allow Python to be more stable, but allow additional features for the communities that are interested in installing an additional ctypes release. I intend to do these changes, the first is a small and trivial one, but allows a lot of flexibility: - Remove the restriction that the argtypes attribute of foreign functions must be ctypes types. Instead they are only required to implement a .fromparam class method. This patch is ok. I will add comments to the patch on SF.

Patch 1517790 is now committed, thanks.

The second one is more involved, and not yet complete. I can post the patch or a link to it for review when it is implemented completely:

- Implement the arraystruct attribute as describes by the numpy pep at http://numpy.scipy.org/arrayinterface.html. This is too much to add to a beta. Perhaps you could work on a branch to add these features and integrate the branch back in after 2.5 has been released. You could make an external release from the branch.

We will see how this works out. Not what I expected to hear, but I'm sure it is a wise decision.

Thanks, Thomas
