If submodules are outdated, it'll panic with the following message
```
Repository is outdated, please run `just submodules` to update it.
```
For us maintainers, we'll need the env `UPDATE_SNAPSHOT` to force an update.
I think `UnusedLabeled` can do more than that.
1. Collect unused label
2. Support check duplication label
3. Support check label in `BreakStatement`
4. Support check label in `ContinueStatement` (Not yet)
But then the `UnusedLabeled` name wouldn't fit, so I renamed it
`LabelBuilder` and moved it to `label.rs`
This PR is part of #1880.
`Token` size is reduced from 48 to 40 bytes.
To reconstruct the regex pattern and flags within the parser , the regex
string is
re-parsed from the end by reading all valid flags.
In order to make things work nicely, the lexer will no longer recover
from a invalid regex.
The regression case in typescript is as expected since we don't
currently store `AccessorProperty` in `ClassTable`.
The following code is one of those cases
```ts
class C1 {
accessor #a: any;
accessor #b = 1;
static accessor #c: any;
static accessor #d = 2;
constructor() {
this.#a = 3;
this.#b = 4;
}
static {
this.#c = 5;
this.#d = 6;
}
}
```
But there was an error
```shell
Expect to Parse: "conformance/classes/propertyMemberDeclarations/autoAccessor2.ts"
× Private field 'a' must be declared in an enclosing class
╭─[conformance/classes/propertyMemberDeclarations/autoAccessor2.ts:9:1]
9 │ constructor() {
10 │ this.#a = 3;
· ──
11 │ this.#b = 4;
╰────
```
Let's leave it alone for now. Because of the `AccessorProperty` I
haven't seen it in any repo.
