I think we have very different philosophies, life agendas and
computer religions. (I wish I had time to write my planned book
of that title.) Nor do I have time to explain why I don't like object-
oriented design or object closure.
Since this is LGPL open source, you're welcome to vary it
any way you like.
My design represents my own religious principles. Religion is beyond
argument; the best outcome is to understand each other cordially.
All best, Ted
