I watched some of this. Some notes on specific criticisms follow. (Many
of the criticisms are too abstract to really confront head-on
though--for example, "correctness versus performance".)
1. *The compiler is too hard to modify.* See my other message in the thread.
2. *Universal equality is bad.* Rust doesn't do it.
3. *Using inheritance for collection mutability is bad.* Rust doesn't do it.
4. *The argument to functions such as "filter" should be pure to allow
for stream fusion.* Purity is hard in Rust. We tried it and the
annotation burden was too high. At least our iterators allow for more
stream fusion than creating intermediate data structures would.
5. *Forbid reference equality.* Incompatible with the systems language
nature of Rust.
6. *Silent coercion between primitives is bad.* Rust doesn't do it.
7. *Don't try to be too general purpose.* Rust is explicitly not
designed to be a language for all use cases.
8. *Unnecessary expressiveness is the enemy.* I think we've been holding
the line on language complexity quite well, even for features that are
popular like `&once fn`.
