Reviewing 44424.diff​:

• $entries and $headers could do with descriptions.
• get_header() returns a header, not an element.
• translate_entry() returns an entry, not an element.
• select_plural_form() returns int, and the return needs a description.
• translate_plural() only returns a string. The params and return need a description.
• gettext_select_plural_form() returns the result of calling the callable that make_plural_form_function() returns. The callable that make_plural_form_function() returns will return an int.
• make_plural_form_function() returns a callable.
• All of the docblocks added to NOOP_Translations need descriptions.
