Maybe Boost.Lambda2 could also provide its own thin wrapper for std::bind which returns a type from namespace boost::lambda2
I think (and hope) that this won't be necessary. By the way, one advantage of Lambda2 defining its own placeholders would be that they will now be usable as function objects. The need for just _1 or _2 as a lambda is surprisingly common and it's an annoyance that they don't work. I was going to add a "wrong" unary plus allowing +_1 to be usable as identity instead of _1, but now this hack won't be needed.
Anyway, at some point you may need to add something like `boost::lambda::constant` to handle cases like `"TIME " + time + _1`.
Yes, maybe. That's bind(identity(), x), and your point is probably that boost::lambda2 is not going to be an associated namespace of it. We'll see.
