I am. I was just wondering if there was an in-progress effort I should be looking at, because I am interested in extensions to it.

P.S.: If anyone is missing the relevance, Raymond Hettinger's compact dicts are inherently ordered until a delitem happens.[1] That could be "good enough" for many purposes, including kwargs and class definition. If CPython implements efficient compact dicts, it would be easier to propose order-preserving (or initially-order-preserving) dicts in some places in the standard.

[1] Whether delitem preserves order depends on whether you want to allow gaps in your compact entry table. PyPy implemented compact dicts and chose(?) to make dicts ordered.

Nope. I presume you are talking the proposal Raymond made a while back. -eric -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.python.org/pipermail/python-dev/attachments/20160613/da63b8b7/attachment.html>
