I think this is a total non-issue for the following reasons:
1. Recall the original philosophy behind the list/tuple split.
Lists and dicts are usually variable-length homogeneous
structures, and therefore it makes sense for them to be
mutable. Tuples are usually fixed-length heterogeneous
structures, and so it makes sense for them to be immutable
and unpackable.
2. In all the Python programs i've ever seen or written, i've
never known or expected a dictionary to have a particular
fixed length.
3. Since the items come back in random order, there's no point
in binding individual ones to individual variables. It's
only ever useful to iterate over the key/value pairs.
In short, i can't see how anyone would ever want to do this.
