Hi,
There has been a lot of interest recently (eg psr-7) in immutable data. I'm
considering putting an RFC together to add language support for immutables:
immutable class Foo {
public $bar;
public function __construct($bar) {
$this->bar = $bar;
}
}
Immutable on a class declaration makes all (maybe only public?) properties
of the class immutable after construct; assigning to a property would
result in a Fatal error.
class Foo {
public $bar;
immutable public $baz;
}
Immutable on a property makes the property immutable once it takes on a
none null value. Attempts to modify the property after this results in a
fatal error.
Any thoughts?
