<blockquote>
<h1>Release rayon 1.8.0 / rayon-core 1.12.0 (2023-09-20)</h1>
<ul>
<li>The minimum supported <code>rustc</code> is now 1.63.</li>
<li>Added <code>ThreadPoolBuilder::use_current_thread</code> to use the
builder thread as
part of the new thread pool. That thread does not run the pool's main
loop,
but it may participate in work-stealing if it yields to rayon in some
way.</li>
<li>Implemented <code>FromParallelIterator<T></code> for
<code>Box<[T]></code>, <code>Rc<[T]></code>, and
<code>Arc<[T]></code>, as well as
<code>FromParallelIterator<Box<str>></code> and
<code>ParallelExtend<Box<str>></code> for
<code>String</code>.</li>
<li><code>ThreadPoolBuilder::build_scoped</code> now uses
<code>std:🧵:scope</code>.</li>
<li>The default number of threads is now determined using
<code>std:🧵:available_parallelism</code> instead of the
<code>num_cpus</code> crate.</li>
<li>The internal logging facility has been removed, reducing bloat for
all users.</li>
<li>Many smaller performance tweaks and documentation updates.</li>
</ul>

This PR introduces the oxc transformer.
The code is purposely arranged without any Rust trickery such as traits
and macros.
I intend to keep the code style this way until something blows up.
The next steps are:
* unit tests
* conformance tests with TypeScript and Babel
* benchmarks

HIR is removed from this PR, with the minifier being commented out.
HIR is a wonderful idea for compiling to lower languages, but after
sitting on it for a few months I found that it only adds confusion and
uncertainties to both myself and future contributors.
It also adds too much burden to maintainers if we plan to support more
downstream tools.
1 AST is the only way.
Fold constant addition expressions. Handles string concatenation and
addition, both with implicit casting.
For example,
```ts
let x = 1 + 1
let y = "hello " + "world"
```
now becomes
```ts
let x = 2
let y = "hello world"
```
## Extra Goodies
- test(minifier): add `test_snapshot` helper to perform snapshot tests
with `insta`
- up(hir): implement `std::ops::Add` for `NumericValue`
- up(span): impl `TryFrom<Cow<'_, &str>>` for `Atom`
relates #709
The allocator and lifetime gets in the way if we want to parse in
parallel but process them in a single thread.
This example uses `ouroboros` to provide a safe API for working with
this unsafe behavior.
