Would it be possible to introduce a general __invoke (Or whatever name is more fitting) magic-method, so that whichever object implements that method, is callable with call_user_func (and directly through variable-function-syntax). Eg.: class Foo { function __invoke($thing) { echo "Foo: " . $thing; } } $foo = new Foo(); $foo("bar"); // > echoes "Foo: bar" I'm not sure how this would play together with lexical scope? -- troels
