Summary:
Cleanup documentation as with the other traversal, no raw loops.
Note: about no raw loops philosophy
To make clear and explicit the intention of the code, in this case to iterate over all elements of a collection.
A raw loop exposes unwanted flexibility which makes it hard to reason about code. A raw loop body thus have control over the lifetime of the loop itself.
- continue
- break
- return
None of those can be used with a forEach for example. Thus we make it clear the intention of the code.
