I don't know whether it is in the stdlib, but I sometimes use tuples as
dict keys. E.g.
mydict[('mertz', 'david')] = 3.1415
Even though I could omit them, I'd almost surely use the parens for that.
And more likely it would be:
name = ('mertz', 'david')
mydict[name] = 3.1415
Conceptually, an "immutable collection" serves a different purpose than "a
collection of axes", even if they work then same under the hood.
