Give a hint on how to remove array's element while iterating over it

Issue description:
Class: Array

I was searching how to iterate through an array to remove/erase some of its elements. When I first read the docs, I understood that erasing while iterating on an array is not possible at all. The first comment of this reddit post advises to loop backward and to use remove_at. I think it would be nice to indicate in the docs that is possible to remove element this way, eventually directly providing a code snippet.

If we're talking using a for loop this isn't possible at all as far as I know, this isn't remove at but erase so it's not index based so doesn't really make sense to erase elements while iterating with erase

Woops my bad, that's not erase it is remove_at, I edit the issue

Then the solution is simple, iterate with a while loop using i < array.size() and don't increment when you remove

There also isn't any such note in remove_at, and it's fine as long as you check the range of values. I don't see how a note is needed here

Because this solution is simple for anyone who already knows it. I think removing elements from an array is a common operation, but it's not intuitive (at least for). I would have appreciated seeing this note in the docs when I was figuring out.

What would the note say? I don't see what situations it would help with?
