Are you implying that we should deprecate the `in` operator for strings
too?
Strings *are* collections:
py> import collections.abc
py> isinstance("spam", collections.abc.Collection)
True
Strings aren't atomic values: they contain substrings. They can be
sliced. We can ask whether one string contains another: strings are
containers as well as collections.
Sometimes we treat strings as if they were pseudo-atomic. And
sometimes we treat tuples as pseudo-atomic records too. Should tuples no
longer be iterable? I don't think so.
