While advancing at least two computer science zen levels I augmented my brain enough to implement the augment method modifier in Joose.
Class("HTMLDoc", { augment: { html: function () { return ""+this.INNER()+"" } } })
Class("HTMLDocBody", { isa: HTMLDoc, augment: { html: function () { return ""+this.INNER()+"" } } })
Class("TPSReport", { isa: HTMLDocBody, augment: { html: function () { return "TPS-Report
" } } })
