I'm -100 now on "deferred evaluation, but contorted to be useless outside of argument declarations."

At first I thought it might be harmless, but nothing I really care about. After the discussion, I think the PEP would be actively harmful to future Python features.

It's nothing more than an implementation detail. If you want to suggest - or better yet, write - an alternative implementation, I would welcome it. Can you explain how this is "actively harmful"? ChrisA
