-===== Proposal ===== +
-A new magic toKey method, to resolve the problem of not being able to use Objects as array keys. +

-<code php> +
-<?php +
-class Foo { +
-    public function __toKey() { +
-        return "Foo"; +
-    } +
-} +
- +
-$foo = new Foo(); +
-$test = [ +
-    $foo => true +
-]; +
-</code> +
- +
-Inheritance shall work as any other magic method: +
- +
-<code php> +
-<?php +
-class Foo { +
-    public function __toKey() { +
-        return "Foo"; +
-    } +
-} +
- +
-class Bar extends Foo { +
-    /* shall use Foo::__toKey unless Bar::__toKey is implemented */ +
-} +
- +
-$bar = new Bar(); +
-$test = [ +
-    $bar => true +
-]; +
-</code> +
- +
-The current behaviour of __toString is unchanged. +
