Sorry, another niggle re handling an empty affix: With your Python
implementation,
'aba'.cutprefix(('', 'a')) == 'aba'
'aba'.cutsuffix(('', 'a')) == 'ab'
This seems surprising.

Much appreciated! I will add that single quote and change those snippets to::
>>> s = 'FooBar' * 100 + 'Baz'
>>> prefixes = ('Bar', 'Foo')
>>> while len(s) != len(s := s.cutprefix(prefixes)): pass
>>> s
'Baz'
and::
>>> s = 'FooBar' * 100 + 'Baz'
>>> prefixes = ('Bar', 'Foo')
>>> while s.startswith(prefixes): s = s.cutprefix(prefixes)
>>> s
'Baz'
