Hello, my personal understanding is that you can use multiple iterative controls (as a merge) in a fo loop, otherwise we can only separate these iterative controls, but in fact, they may do the same thing.
2. I understand the functionality, but I don't think there is a real necessity to support this functionality. Not in this static form, and just for integer type.
Postgres has a nice generic type "multirange". I can imagine some iterator over the value of multirange, but I cannot imagine the necessity of a richer iterator over just integer range. So the question is, what is the real possible use case of this proposed functionality?

Hi
ok, I was wrong, PL/SQL supports this syntax. But what is the real use case? This is an example from the book.

Hello, this usage scenario is from Oracle's PL/SQL language (I have been doing the function development of PL/SQL language for some time). I think this patch is very practical and will expand our for loop scenario. In short, I look forward to your
I don't see any real usage. PL/SQL doesn't support proposed syntax.
Maybe you didn't understand my reply. Without some significant real use case, I am strongly against the proposed feature and merging your patch to upstream. I don't see any reason to enhance language with this feature.
