doc_updater = setdoc("This function adds two numbers.")

# Apply it to a target function
@doc_updater
def add(a: int, b: int) -> int:
    return a + b

# The function now has an updated docstring
print(add.__doc__)
# Output: This function adds two numbers.

# Apply it directly to another target function
@setdoc("This function multiplies two numbers.")
def mul(a: int, b: int) -> int:
    return a * b

# The function now has an updated docstring
