Exactly my motivation with COPA as well;
- Typed properties - check,
- Reduce boilerplate - check,
- Initializing and setting properties in one expression - check.

And with COPA it would be;
$this->dispatch((new SomeCommand)->[ foo = 'bar', baz = false ]);
Subtle differences, when compared to the currently available alternative.

Maybe you missed that COPA can be combined with object construction?

Exactly, and as I couldn't help notice that you voted for the Write
Once Properties RFC, which clearly states that
object construction is a fuzzy term (meaning don't take it too
seriously) and lazy initialization is a feature...
I hope you will either reconsider your support for COPA or let me know
what I'm missing so I can
consider other directions.
