What kind of changes have been needed to make it possible to implement
coroutine and generator?

I see 3 valid alternatives here:
* You provide it as sub-library coroutine of context.
* You request for review a separated coroutine proposal.
* You rename your context library as cooperative/context and add the
cooperative/coroutine, cooperative/fiber, ..... This will need at least a
mini-mini review to change the goal, the name and the directory of the
library. This alternative would not prevent to request less formal review or
formal ones if you find it useful. I would prefer a change the top level
namespace to cooperative in this case.
The alternatives are in the reverse order of my preference.
I agree with Jeffrey that we need less top level libraries, and have
sub-libraries. For example Boost.Thread contains the review accepted
Boost.Futures. Is this clearer for the users?
I would like to have e.g. under the umbrella of Boost.Utility 'everything'
that 'every' programmer needs.
I don't know yet if Boost.Chrono will include or not a Stopwatch or a Date
(not a DateTime) sub-library but I think at least an informal review would
be needed to ensure the Boost quality. This will give the opportunity to
the Boost community to signal if a formal review will be more convenient.
