yes, this coding pattern is very troublesome. It's a good thing I like challenges huh? I will be happy, in this discussion, if we can accept that the real differences we must master are our philosophy and reference models (which are tightly tied together); these are real differences. We should not ignore the engineering differences - but these can be solved if we want > this is true.

Not easy, never easy to make progress, but the glaciers are moving. Grahame
