Function signature mismatch for `functools.reduce` between C implementation, Python implementation, and online documentaion

Documentation

(A clear and concise description of the issue.)

The function signature mismatch for functools.reduce:

• C implementation:

  _initial_missing = object()
  
  @overload
  def reduce(function, iterable, /): ...
  @overload
  def reduce(function, iterable, initial=_initial_missing, /): ...

• Python implementation:

  _initial_missing = object()
  
  @overload
  def reduce(function, sequence): ...
  @overload
  def reduce(function, sequence, initial=_initial_missing): ...

Argument change: iterable -> sequence.

• Online documentation:

  def reduce(function, iterable, initializer=None): ...

Argument change: initial -> initializer.
