## Summary Resolves #15695, rework of #15704. This change modifies the Mdtests framework so that: * Paths must now be specified in a separate preceding line: `````markdown `a.py`: ```py x = 1 ``` ````` If the path of a file conflicts with its `lang`, an error will be thrown. * Configs are no longer accepted. The pattern still take them into account, however, to avoid "Unterminated code block" errors. * Unnamed files are now assigned unique, `lang`-respecting paths automatically. Additionally, all legacy usages have been updated. ## Test Plan Unit tests and Markdown tests. --------- Co-authored-by: Carl Meyer <carl@astral.sh>

Function shadowing
Parameter
Parameter x of type str is shadowed and reassigned with a new int value inside the function.
No diagnostics should be generated.
a.py:
def f(x: str):
x: int = int(x)
Implicit error
a.py:
def f(): ...
f = 1 # error: "Implicit shadowing of function `f`; annotate to make it explicit if this is intentional"
Explicit shadowing
a.py:
def f(): ...
f: int = 1
Explicit shadowing involving def statements
Since a def statement is a declaration, one def can shadow another def, or shadow a previous
non-def declaration, without error.
f = 1
reveal_type(f) # revealed: Literal[1]
def f(): ...
reveal_type(f) # revealed: Literal[f]
def f(x: int) -> int:
raise NotImplementedError
reveal_type(f) # revealed: Literal[f]
f: int = 1
reveal_type(f) # revealed: Literal[1]
def f(): ...
reveal_type(f) # revealed: Literal[f]
