I've installed the various packages, read the tutorial and reviewed the code in the new request monitor. I'm far from grok-level understanding but am fairly enthusiastic about what I'm seeing.
I believe there are definitely places in standard oacs that could benefit from this style of programming. There are also potential pitfalls like object-relational mapping which most OO roads trend towards.
I agree pretty strongly with a lot of the statements above, particularly Andy P's comment and Dave B's point that a strong proposal would identify where to apply it. The ideal candidates would be places that could really be improved, not just re-coded. For example site node resolution.
I will comment on the TIP after I've had a bit more time to think and tweak.
