'MOP' has been my go-to paradigm for most of my professional career. I freely admit that I 'go there' too soon in some situations, but you are quite correct about the benefits.
Scalability is only one benefit. Testability is another. And my favorite, it's very easy and usually safe to do run-time hacks, as the need arises.
I am currently working on a wide-scale, multi-language MOP family of libraries that I hope will make this programming paradigm a lot more accessible.
hey, i'm playing with some MOP like systems on the side myself. I haven't figured out how to make the code language independent yet but have ideas. Most of it is mostly exploratory. If you are interested in a discussion, contact me. It would be cool to discuss witha like-minded engineer.
