> I have a question for you. How do you think we could use this pattern in the generalised situation:

In general ;-) I like things that can be used universally much more than a huge number of special cases.
But here, I'm not sure if it's not an increase of complexity:

I often if statements with several stages of unpacking, and when there is something similar for loops, imho it should act in the same way:
for let array? = test,  i in array {

This would preserve the right order and keep the where clause reserved as it is now.
