[New-bugs-announce] [issue18813] Speed up slice object processing

[Stefan Behnel]

New submission from Stefan Behnel:

The get/set/delitem slicing protocol has replaced the old Py2.x get/set/delslice protocol in Py3.x. This change introduces a substantial overhead due to processing indices as Python objects rather than plain Py_ssize_t values. This overhead should be reduced as much as possible.

This ticket can be seen as a more general follow-up to issue10227.
