My old programming language project, Unimperative, has been reborn as a "concatenative" programming language in the tradition of Joy.

Part of the problem of not specifying what an object depends on, is that its dependencies can violate its invariants. This results in a program that Brian Shearing calls the "Calls-Out-The-Back" problem.

Okay Joy has more than two problems, but two problems really stick out.

A colleague of mine, Peter Grogono, brought to my attention recently the overlooked backside of interfaces.

I have recently discovered the somewhat unknown and understated language, Joy. A pure functional language, without lambda operations!

In of itself not that exciting, but it can enable some interesting paradigms.

In a recent discussion Kresimir Cosic said the following thing to me: "I think that subtyping a-posteriori is great.". When thinking about case classes ala Scala (which I believe was inspired by Haskell), I couldn't help but wonder, why not have case classes a-posteriori?

Good question. Here is a brief summary of where I'm at and where I'm thinking of going.

I don't know any language which is so perverse as to do such a thing, but I want to throw it out there as an idea to torment people.

I thought I would share my latest attempt at writing a white paper describing the implicit behavioral subtyping mechanism I am using for the current Heron prototype (yes you can download it at http://www.heron-language.com/ ). Any comments would be appreciated.

The latest HeronFront prototype now provides traits which support structural subtyping (duck typing), and behavioral subtyping. This extensions should prove very interesting to people who are interested in agile programming methodologies, and programming with contracts.

I made a mistake in my latest Agile C++ article for C++ Users Journal, and I want to retract it.
