This manifesto outlines a plan to add compound types corresponding to fixed-size scoped-storage homogenous containers.
Array. Possibly other members too.

This manifesto is for collecting the ideas needed to introduce the classic fixed-size array family of types to Swift.
During the review process, add the following fields as needed:
| // ForEachIndex.swift by Daryle Walker | |
| extension Collection { | |
| /** | |
| Calls the given closure on each element index in the collection in the | |
| same order as a `for`-`in` loop. | |
| The two loops in the following example produce the same output: |
