Mixins with include in AS3

Test.as

// ActAsDog.as

public function bark(): void
{
	trace("bark");
}

// ActAsCat.as

public function meow(): void
{
	trace("meow");
}


// CatDogHybrid.as
package
{
	class CatDogHybrid
	{
		include "ActAsCat.as"
		include "ActAsDog.as"
	}
}

// Test.as

var hybrid = new CatDogHybrid();
	hybrid.meow() // meow
	hybrid.bark() // bark

:) Me too - apart from higher-order typing for functions the lack of mixins (or, much better yet: traits) is my single-most important gripe with the language.
