Hi Everyone,
In the meanwhile, I changed my proposal to use [] instead of {} after the
"with" clause due to its better receptance.
Additionally, I removed support for the shorthand "property assignment"
syntax (clone $this with [property1: "foo"]) in
favor the more powerful one where the left-hand side supports expressions
(clone $this with ["property1" => "foo"])
so that we have more time to decide whether the former one is really needed.
After talking with Nicolas and Alexandru off-list (I accidentally didn't
click "Reply All" in my response), we identified
that their "clone callback" proposal could also be a future-scope of the
current RFC with the following syntax:
clone $this with function (object $clone): void {
$this->property1 = "foo";
}
In my opinion, this syntax is OK, albeit it's a bit long to write and a bit
difficult to decipher its meaning (maybe it's
just me). That's the main reason I prefer my originally proposed syntax.
Apart from this, I don't see a big issue with it,
neither conceptually, nor with the implementation.
Regards,
Máté
