Thank you very much; all of that is very gratifying to hear.

And yes, being conservative about what we add to the standard library is a very deliberate decision. We also try not to do novel design in the standard library; design and iteration should happen in the ecosystem.

There are also some things that we're unlikely to ever add, such as cryptographic algorithms, precisely because we wouldn't be confident that we could fix issues with them without breaking compatibility. Crates in the ecosystem get to have a 2.0; the standard library doesn't. (Editions give us some ability to evolve the standard library, but the standard library still has to support every past edition.)

Also: I wish this level of discourse were what we could have with everyone who expresses a dislike of Rust. This has been an entirely pleasant experience, and I appreciate your feedback. Even if Rust isn't your particular cup of tea and you'd prefer to write your own code in something else, I'm gratified to know that things like this make it more tolerable. We often have to deal with code in languages that aren't our first choice.
