I'm not getting it. What's the point? It seems very much like a cpp-ism where you can put
const
in so many places.Then there are constant expressions.
Can anybody look at that and tell me it's readable with a straight face? I hope they don't start adding all this stuff to rust.

It can be used for producing const values in arbitrary context. Can basically be swapped for c++'s constexpr.
C++'s const does not exist in rust (values are const by default).
Nope. This little neat feature mainly is just necessary part of bigger one - const-generics with const bounds.
