I agree, the runkit is excellent but has to be deeply integrated to the
language - for example, add methods to the Reflection extension to find out
which methods added by extension methods etc.

Regard the implementation - I saw and used several ways of implementing it,
and do think that because one of the important pros of PHP is the language
writing style which is nice and clean - we should think of good syntax.

for example, C# request to add "this" keyword before each extension method,
and require the class and methods to be static - for instance:
public static class Bar {
     public static void bar(this Foo obj) { }
     public static int baz(this Foo obj, int bar);
}

new Foo().baz(1);
