## Summary
Split the "Generator functions" tests into two parts. The first part
(synchronous) refers to a function called `i` from a function `i2`. But
`i` is later redeclared in the asynchronous part, which was probably not
intended.
## Summary
Resolves https://github.com/astral-sh/ty/issues/339
Supports having a blank function body inside `if TYPE_CHECKING` block or
in the elif or else of a `if not TYPE_CHECKING` block.
```py
if TYPE_CHECKING:
def foo() -> int: ...
if not TYPE_CHECKING: ...
else:
def bar() -> int: ...
```
## Test Plan
Update `function/return_type.md`

## Summary
Partially implement https://github.com/astral-sh/ty/issues/538,
```py
from pathlib import Path
def setup_test_project(registry_name: str, registry_url: str, project_dir: str) -> Path:
pyproject_file = Path(project_dir) / "pyproject.toml"
pyproject_file.write_text("...", encoding="utf-8")
```
As no return statement is defined in the function `setup_test_project`
with annotated return type `Path`, we provide the following diagnosis :
- error[invalid-return-type]: Function **always** implicitly returns
`None`, which is not assignable to return type `Path`
with a subdiagnostic :
- note: Consider changing your return annotation to `-> None` or adding a `return` statement
## Test Plan
mdtests with snapshots to capture the subdiagnostic. I have to mention
that existing snapshots were modified since they now fall in this
category.
