[Python-Dev] PEP 563: Postponed Evaluation of Annotations

Alright, we're on bikeshed territory now. Finally! :-)

I was always thinking about this as "static annotations". The fact they're strings at runtime is irrelevant for most people who will use this future. They don't want string annotations, they want them to not be evaluated on import time... they want them to be static. Also, "static typing" et al. I think it has a nice vibe to it.

I admit "annotations" is too broad but "static_annotations" (or "string_annotations" ¯\_(ツ)_/¯ ) will be the longest __future__ name so far. That was my main motivation behind using the shorter name. And a bit of megalomania I guess.
