- You have tuples, a fixed size array of elements.
- You can access them by a random index.
- There is no syntax to access a random index of a tuple
- Pattern matching requires you to know the length of the tuple up-front
I think it makes sense to have such a function be part of the standard library. The reasoning is quite simple: if you provide a builtin data structure, it makes sense to provide an API to read and write to it.
Wether or not it’s idiomatic to access a random element of a tuple is a whole different topic.
