Josh Rosenberg added the comment: Side-note: Some of the objections to a C level namedtuple implementation appear to be based on the maintenance hurdle, and other have noted that a structseq-based namedtuple might be an option. I have previously attempted to write a C replacement for namedtuple that dynamically created a StructSequence. I ran into a roadblock due to PyStructSequence_NewType (the API that exists to allow creation of runtime defined structseq) being completely broken (#28709).
If the struct sequence API was fixed, it should be a *lot* easier to implement a C level namedtuple with minimal work, removing (some) of the maintenance objections by simply reducing the amount of custom code involved. The testnewtype.c code attached to #28709 (that demonstrates the bug) is 66 lines of code, and implements a basic C level namedtuple creator function (full support omitted for brevity, but aside from _source, most of it would be easy). I'd expect a finished version to be low three digit lines of custom code, a third or less of what the cnamedtuple project needed to write the whole thing from scratch. ---------- nosy: +josh.r _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28638> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
