I would prefer to put lazy as a keyword in pytokens instead of working around the grammar. Would you mind if I did that change on top?

After rethinking, I am happy with doing this in black. pytokens will mimic cpython for lazy being NAME tokens.

### Release Notes

<details>
<summary>psf/black (black)</summary>

### [`v26.5.0`](https://github.com/psf/black/blob/HEAD/CHANGES.md#Version-2650)

[Compare Source](psf/black@26.3.1...26.5.0)

##### Highlights

- Add support for unpacking in comprehensions (PEP 798) and for lazy imports (PEP 810),
  both new syntactic features in Python 3.15 ([#&#8203;5048](psf/black#5048))
- Python 3.15 is now supported. Compiled wheels are not yet provided for Python 3.15, so
  performance may be slower than on existing Python versions. Wheels will be provided
  once Python 3.15 is later in its release cycle. ([#&#8203;5127](psf/black#5127))

##### Stable style

- Fix `# fmt: skip` being ignored in nested `if` expressions with parenthesized `in`
  clauses ([#&#8203;4903](psf/black#4903))
- Add syntactic support for Python 3.15 ([#&#8203;5048](psf/black#5048))
- Fix crash when an f-string follows a `# fmt: off` comment inside brackets ([#&#8203;5097](psf/black#5097))
- Preserve multiline compound statement headers when `# fmt: skip` is placed on the
  colon line ([#&#8203;5117](psf/black#5117))

##### Preview style

- Improve heuristics around whether blank lines should appear before, within and after
  groups of same-name decorated functions (such as `@overload` groups) in `.pyi` stub
  files ([#&#8203;5021](psf/black#5021))
- Fix blank lines being removed between a function and a decorated class in `.pyi` stub
  files ([#&#8203;5092](psf/black#5092))
- Prevent string merger from creating unsplittable long lines when a pragma comment
  (e.g. `# type: ignore`) follows the closing bracket ([#&#8203;5096](psf/black#5096))

##### Packaging

- Run CI on 3.15 ([#&#8203;5127](psf/black#5127))

##### Output

- Improve parse error readability by showing multi-line output with an error pointer.
  ([#&#8203;5068](psf/black#5068))
- Add `SourceASTParseError` to distinguish source parse failures from internal safety
  errors, improving error reporting when Black's lenient parser accepts input that
  `ast.parse()` rejects ([#&#8203;5080](psf/black#5080))

##### *Blackd*

- Return HTTP 400 (Bad Request) for source parse failures instead of HTTP 500, keeping
  HTTP 500 only for genuine internal safety errors ([#&#8203;5080](psf/black#5080))

##### Integrations

- Added documentation for doctest formatting tools and updated the integrations index to
  match ([#&#8203;4916](psf/black#4916))

##### Documentation

- Use "Version X.Y.Z" headings in changelog for stable permalink anchors on ReadTheDocs
  ([#&#8203;5063](psf/black#5063))
- Note in the editor integrations that the SublimeText `sublack` plugin is archived and
  unmaintained ([#&#8203;5082](psf/black#5082))

### Release Notes

<details>
<summary>psf/black (black)</summary>

### [`v26.5.0`](https://github.com/psf/black/blob/HEAD/CHANGES.md#Version-2650)

[Compare Source](psf/black@26.3.1...26.5.0)

##### Highlights

- Add support for unpacking in comprehensions (PEP 798) and for lazy imports (PEP 810),
  both new syntactic features in Python 3.15 ([#&#8203;5048](psf/black#5048))
- Python 3.15 is now supported. Compiled wheels are not yet provided for Python 3.15, so
  performance may be slower than on existing Python versions. Wheels will be provided
  once Python 3.15 is later in its release cycle. ([#&#8203;5127](psf/black#5127))

##### Stable style

- Fix `# fmt: skip` being ignored in nested `if` expressions with parenthesized `in`
  clauses ([#&#8203;4903](psf/black#4903))
- Add syntactic support for Python 3.15 ([#&#8203;5048](psf/black#5048))
- Fix crash when an f-string follows a `# fmt: off` comment inside brackets ([#&#8203;5097](psf/black#5097))
- Preserve multiline compound statement headers when `# fmt: skip` is placed on the
  colon line ([#&#8203;5117](psf/black#5117))

##### Preview style

- Improve heuristics around whether blank lines should appear before, within and after
  groups of same-name decorated functions (such as `@overload` groups) in `.pyi` stub
  files ([#&#8203;5021](psf/black#5021))
- Fix blank lines being removed between a function and a decorated class in `.pyi` stub
  files ([#&#8203;5092](psf/black#5092))
- Prevent string merger from creating unsplittable long lines when a pragma comment
  (e.g. `# type: ignore`) follows the closing bracket ([#&#8203;5096](psf/black#5096))

##### Packaging

- Run CI on 3.15 ([#&#8203;5127](psf/black#5127))

##### Output

- Improve parse error readability by showing multi-line output with an error pointer.
  ([#&#8203;5068](psf/black#5068))
- Add `SourceASTParseError` to distinguish source parse failures from internal safety
  errors, improving error reporting when Black's lenient parser accepts input that
  `ast.parse()` rejects ([#&#8203;5080](psf/black#5080))

##### *Blackd*

- Return HTTP 400 (Bad Request) for source parse failures instead of HTTP 500, keeping
  HTTP 500 only for genuine internal safety errors ([#&#8203;5080](psf/black#5080))

##### Integrations

- Added documentation for doctest formatting tools and updated the integrations index to
  match ([#&#8203;4916](psf/black#4916))

##### Documentation

- Use "Version X.Y.Z" headings in changelog for stable permalink anchors on ReadTheDocs
  ([#&#8203;5063](psf/black#5063))
- Note in the editor integrations that the SublimeText `sublack` plugin is archived and
  unmaintained ([#&#8203;5082](psf/black#5082))
