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.
def f(x: str):
x: int = int(x)
Implicit error
def f(): ...
f = 1 # error: "Implicit shadowing of function `f`; annotate to make it explicit if this is intentional"
Explicit shadowing
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.
