modified: pandas/core/reshape/pivot.py

	- Added ignore-comment to silence mypy error in :func:`__internal_pivot_table`.
	- Added TODO-comment stating that the :meth:`DataFrameGroupBy.__getitem__` should be overloaded to match the pandas-stubs type declarations, informing mypy that the type is correct given `values` is a list.
