What I propose is to add a pointer "ma_extra" (same 64bits), which will be set to NULL for most dict instances (instead of ma_version). "ma_extra" can then point to a struct that has a globally unique dict ID (uint64), and a version tag (unit64).
Why not just use a single global counter for allocating dict version tags, instead of one per dict?
Yeah, I think that's what we agreed on: https://mail.python.org/pipermail/python-dev/2016-January/142837.html The only advantage of ma_extra pointer is that it allows to add more stuff to dicts in the future. Yury
