I think everyone can agree this is useful. But the issue here is the
implementation.
Because from what I know PHP's references are a special kind of pain in the
engine.

That's why the common wisdom is to use references in PHP as least as
possible.
And IIRC what you are trying to achieve would need a major overhaul of how
references
work and someone who wanted to tackle this would have done it on their own
and
propose an RFC at the same time.

So sadly unless something semi-concrete shows up, I'm considering this a
pipe dream.
But I'd gladly be shown otherwise.

Best regards
