Looks like this was just a stupid mistake I made. Stupid mistakes like this are why the test suite is so important.

This isn't actually fixed yet.

this doesn't parse:

```
int bar() {
    int foo;
    foo++;
}
```

I think I had a crash yesterday when writing a loop like this:

```
for (uint I = 0; I < n; I++)
```

and had to instead write it like
```
for (uint I = 0; I < n; I = I + 1)
```

Looks like the new test webgpu/whlsl-read-modify-write.html
added in https://trac.webkit.org/changeset/246681/webkit

is missing results on WK2
