The entry in the glossary for "hashable" (https://docs.python.org/3/glossary.html#term-hashable) states "All of Python’s immutable built-in objects are hashable." Tuples are described as immutable sequence types (https://docs.python.org/3/library/stdtypes.html#immutable-sequence-types), but they are not hashable unless all of their elements are hashable. Suggest updating the glossary to reflect this.

For that matter, slices are immutable built-ins, but they're not hashable (presumably to avoid silently working with dictionaries in a non-slice capacity).
