Hello,
I'm trying to register a var through a dynamical use of "register" (I mean
: using a var, like : register: {{ var }}).
Dev updated the code and removed this option (now static only).
I'm not able to find more information about that change and also there is
nobody connected on the IRC so, I post here.
Bug report (closed without real details) :
https://github.com/ansible/ansible/issues/57839
Code change :
https://gitlab.ics.muni.cz/242618/ansible/commit/be776daefed047f0bd45d7441efde046677fd417
The very detailed comment about that (from the bug report) :

This is expected and we will never allow this behavior. Register must use a
statically defined string.
If you have further questions please stop by IRC or the mailing list:

That's it, no more information, I don't understand why and now I'm stuck in
my Ansible configuration.
I was trying to create a loop of 4 tasks (function like), I'm able to pass
any vars to those tasks (using separated include: and loop:).
But all this is useless if I can't register results in "dynamically
selected" variable name.
Final results are input for a template (just after that include task).
So, I have now a "working" function, able to consume any var already
defined ... but can only register to a unique var (very very useful when
you are in a loop with MULTIPLE elements and not only 1).
Can someone explain me why this change of behavior and how am I supposed to
make it works now without the option to "register: {{ my_var }} ?
Let me copy past my configuration so that it will be easier to understand.
What I see with that change to static register : can't loop on tasks
anymore (or only for basic use).
Pelase let me know how I'm supposed to do that in "a compact way" now (I
was trying to move from 5x blocks of 4 tasks to 1 include (with loop) of 4
tasks).

How should I do now to avoid all my duplicated blocks ?
Thanks,
Laurent
