Indeed, I was missing you in the whole discussion Joel :)

I hope my last post sched some more light on it.

Agreed. It really is only about tweaking the "low level" part of phoenix.
The high level customization point (phoenix::function) is already here.
Although most of the stuff is working already there is still need for some
tweaks:
- Boost.Bind compatibility is not yet complete (around 90% is done)
- phoenix::lambda is currently not always working as expected (there are
some minor bugs that needs to be tackled)
