```

bpo-43149 currently calls it an "exception group", but that conflicts with PEP
654 -- Exception Groups and except*

for your usecase I'd write:
def delayed_fstring(*, name: str) -> str:
return "The current name is {name}"
def new_scope() -> None:
for name in ["foo", "bar"]:
print(delayed_fstring(name=name))
for logging I use:
class Msg:
def __init__(self, fn: Callable[[], str]):

What about using a coroutine of `v = yield (name, scope)` so the caller can
choose how and when names are resolved?

I think as long as there's a test case for something like
```
@dataclass
class Node:
global_node: ClassVar[Node | None]
left: InitVar[Node | None]
right: InitVar[None | None]

I don't think I've seen code like this. It would be incredibly useful to have a

I don't think the python syntax should be beholden to syntax highlighting
tools, eventually some syntax feature that PEG enables will require every
parser or highlighter to switch to a similar or more powerful parse tool

I think that's unfortunate, you can still use and format the subset of Python
3.10 syntax with black.
You already do this on python 3.9 for example black doesn't support
