Shouldn't that new API function (whatever its name) also be somehow
exposed for easy access from Python code? I realize new builtins are
unpopular, so a builtin 'asindex' might not be appropriate, but
perhaps operator.asindex might be. My main point is that I don't think
we want every Python-coded sequence to have to call x.__index__()
instead.
