Is this link part of the review? I don't believe, so could you point me
where the monad class is documented in AFIO? If it is not documented,
why it is used so broadly.

Where can I find the description of this macro on the reference
documentation?

If class monad is not included in AFIO, the documentation shouldn't use it.

I've already post in this ML some of my concerns respect to this class.

I would prefer to don't need to do that. You say that monad is like a
shared_future ready, so why don't you just replace the uses of monad by
shared_future<T> in the documentation so we know of what we are talking of.
Sorry but I can not review a document that makes reference to things
that are not yet adopted by Boost.
We have two options:
* we wait to review AFIO once Monad is reviewed in Boost
* You include in AFIO, whatever you consider is need from Monad and only
then we review AFIO.
Best,
