May I stupidly ask, why one would want to use an iterable (even immutable)
as dict key?
A string is also an immutable iterable, so this is probably even the
most common case.

As for more complex data structures:

* Tuples or immutable dicts are a good fit if want to group records by
   subset of their attributes (think "group by" in SQL)

* Objects in general are often though of as units, even if they have
   composite values and you might want to look up something by that
   value.
