Upcoming const breakthrough
I noticed that in the past week or two, Rust team has been pushing a breakthrough with const Trait and const *Fn which gates pretty much everything from Ops, Default, PartialEq, Index, Slice, From, Into, Clone ... etc.
Now the nightly rust is actively populating itself with tons of const changes which I appreciated so much. I'd like to thank all of the guys who made the hard work and spearheaded these features.
