Creating Classes

New classes are created with Class.new (Class is a metaclass, used to create new classes):

    var MyClass =
        Class.new({
            name: "MyClass",
            doc: "Description of MyClass",
            supers: [ SuperClass, .... ],
            methods: {
                name: function (this, ...) { ... }
                ...
            },
            unops: {
                "!": function (this) { ... }
                ...
            },
            binops: {
                "+": function (l, r) { ... }
                ...
            },
            lhsops: {
                ".": function(l, r, value) { ... }
                ...
            },
	    props: {
		class_member: value,
		static_method: function (args) { ... }
	    }
        })

• lhsops methods are called when the binary operator is on the left hand side of an ASSIGNOP, and are passed the value to store, and must return that value.

• "." on an Object (on the right hand side of an ASSIGNOP) will return a callable BoundMethod if the NAME is found as a method.

• All classes should provide "str" and "repr" methods, and an "init" method IFF you want to pass anything to MyClass.new

• To create a singleton class (one with only one instance), use metaclass SingletonClass (use SingletonClass.new instead of Class.new).
