		//
		//		Mixin ancestors provide a type of multiple inheritance.
		//		Prototypes of mixin ancestors are copied to the new class:
		//		changes to mixin prototypes will not affect classes to which
		//		they have been mixed in.
		//
		//		Ancestors can be compound classes created by this version of
		//		declare(). In complex cases all base classes are going to be
		//		linearized according to C3 MRO algorithm
		//		(see http://www.python.org/download/releases/2.3/mro/ for more
		//		details).
		//
		//		"className" is cached in "declaredClass" property of the new class,
		//		if it was supplied. The immediate super class will be cached in
		//		"superclass" property of the new class.
		//
		//		Methods in "props" will be copied and modified: "nom" property
		//		(the declared name of the method) will be added to all copied
		//		functions to help identify them for the internal machinery. Be
		//		very careful, while reusing methods: if you use the same
		//		function under different names, it can produce errors in some
		//		cases.
		//
		//		It is possible to use constructors created "manually" (without
		//		declare()) as bases. They will be called as usual during the
		//		creation of an instance, their methods will be chained, and even
		//		called by "this.inherited()".
		//
		//		Special property "-chains-" governs how to chain methods. It is
		//		a dictionary, which uses method names as keys, and hint strings
		//		as values. If a hint string is "after", this method will be
		//		called after methods of its base classes. If a hint string is
		//		"before", this method will be called before methods of its base
		//		classes.
		//
		//		If "constructor" is not mentioned in "-chains-" property, it will
		//		be chained using the legacy mode: using "after" chaining,
		//		calling preamble() method before each constructor, if available,
		//		and calling postscript() after all constructors were executed.
		//		If the hint is "after", it is chained as a regular method, but
		//		postscript() will be called after the chain of constructors.
		//		"constructor" cannot be chained "before", but it allows
		//		a special hint string: "manual", which means that constructors
		//		are not going to be chained in any way, and programmer will call
		//		them manually using this.inherited(). In the latter case
		//		postscript() will be called after the construction.
		//
		//		All chaining hints are "inherited" from base classes and
		//		potentially can be overridden. Be very careful when overriding
		//		hints! Make sure that all chained methods can work in a proposed
		//		manner of chaining.
		//
		//		Once a method was chained, it is impossible to unchain it. The
		//		only exception is "constructor". You don't need to define a
		//		method in order to supply a chaining hint.
		//
		//		If a method is chained, it cannot use this.inherited() because
		//		all other methods in the hierarchy will be called automatically.
		//
		//		Usually constructors and initializers of any kind are chained
		//		using "after" and destructors of any kind are chained as
		//		"before". Note that chaining assumes that chained methods do not
		//		return any value: any returned value will be discarded.
		//
		// example:
		//	|	declare("my.classes.bar", my.classes.foo, {
		//	|		// properties to be added to the class prototype
		//	|		someValue: 2,
		//	|		// initialization function
		//	|		constructor: function(){
		//	|			this.myComplicatedObject = new ReallyComplicatedObject();
		//	|		},
		//	|		// other functions
		//	|		someMethod: function(){
		//	|			doStuff();
		//	|		}

			// summary:
			//		Calls a super method.
			// name: String?
			//		The optional method name. Should be the same as the caller's
			//		name. Usually "name" is specified in complex dynamic cases, when

			//		declare(), and it cannot be determined.
			// args: Arguments
			//		The caller supply this argument, which should be the original
			//		"arguments".
			// newArgs: Object?
			//		If "true", the found function will be returned without
			//		executing it.
			//		If Array, it will be used to call a super method. Otherwise
			//		"args" will be used.
			// returns:
			//		Whatever is returned by a super method, or a super method itself,
			//		if "true" was specified as newArgs.
			// description:
			//		This method is used inside method of classes produced with
			//		declare() to call a super method (next in the chain). It is
			//		used for manually controlled chaining. Consider using the regular
			//		chaining, because it is faster. Use "this.inherited()" only in
			//		complex cases.
			//
			//		This method cannot me called from automatically chained
			//		constructors including the case of a special (legacy)
			//		constructor chaining. It cannot be called from chained methods.
			//
			//		If "this.inherited()" cannot find the next-in-chain method, it
			//		does nothing and returns "undefined". The last method in chain
			//		can be a default method implemented in Object, which will be
			//		called last.
			//
			//		If "name" is specified, it is assumed that the method that
			//		received "args" is the parent method for this call. It is looked
			//		up in the chain list and if it is found the next-in-chain method
			//		is called. If it is not found, the first-in-chain method is
			//		called.
			//
			//		If "name" is not specified, it will be derived from the calling
			//		method (using a methoid property "nom").
			//
			// example:
			//	|	var B = declare(A, {
			//	|		method1: function(a, b, c){
