Hello,
I voted no as the syntax is too confusing. It reads as if coalescing would
happen on the var while it happens on the array value.
It means $a ?? 'value' would mean something different when in a list context.
It also looks wrong with keys:
list("name" => $name ?? "unknown") = json_decode($json) ?: [];
I would expect:
list("name" ?? "unknown" => $name) = json_decode($json) ?: [];
But event then it looks fishy since "name" is a key and "unknown" is a value.
I understand the need but I just can’t see a good syntax for it, and the one
chosen in the RFC sure feels not good enough for integration.
