use Perl

Joose now supports two new ways to create Joose.Classes

joosify(MyClass) now turns regular classes into Joose.Clases.

...and you can now use a more JavaScript like Syntax to build Joose.Classes:

Class("Currency", {
    does: Eq,
    has:  ["value", {is: rw}],
    methods: {
        initialize: function (value) {
            this.setValue(value)
        },

        isEqual: function (cur) {
            return this.getValue() == cur.getValue()
        }
    }
})
