I'm not saying someone should add decltype :) Just that from using the
iterators we have now it becomes quite obvious that there are missing
tools to use them to the fullest extend.
Is `proc` not sufficient? We could prioritize adding unboxed closures,
but since they're backwards compatible as far as I know, I don't see a
major need to add them before 1.0.
Procs can be called once.
It'd be best to file specific issues here. I'm sympathetic to wanting to
adding more features if they're necessary, but none of the *specific*
things mentioned in this post seem like blockers to me.
I will surely file issues for things that i encounter. It's just that I
was a bit surprised to see that there are ambitions to stabilize the
language quickly. It just feels like that might be to early.
Being active in the Python community I can tell you that a Python 3.0
was the worst decision ever. It would be a shame if a Rust 2.0 suffers
from the same problems.

Armin
