nunny 0.2.2

//! There should be an `impl` here that corresponds to every [`PartialEq`]
//! implementation in [`std`] between:
//! - `[T; N]`
//! - `[T]`
//! - [`Vec`](alloc::vec::Vec)
//!
//! Here's the methodology:
//! - Use the `gen` tool in this repository to scrape rustdoc
//!   (HTML, not JSON - it's much easier)
//! - Output the `test/try_from.rs` file in this repository.
//!   This is effectively a description of the standard library conversions.
//! - Redact unstable items, and implementations we can't do because we're not std.
//! - Switch the types from the standard library to our libraries.
//! - Write implementations _in the same order_ in this file.
