Yes, I do anticipate interface-breaking changes. The proto port (What
we call V3) is special because it actually captures a lot of what I
had in mind for the next revision. I also expect, as typical with
a review, more changes that I haven't foreseen. The suggested "optional-
laziness" and the new and improved switch_ syntax, are two such cases
of high consideration. I thought it would make sense to addess all
these in one step.

Again, let me reiterate, that despite all these changes, the design
and implementation or V2 is still sound, and IMO, pretty much up
to standards with Boost quality. It is still the solid basis for
V3 with up to 95% of the interface intact and essentially unchanged
design and structure.
