* Can be used to specialize the asynchronous control flow
on immediate available asynchronous results mostly returned by:
- make_ready_continuable
- make_exceptional_continuable
* Usable to avoid longer unnecessary synchronous callback nestings.
* cti::query_arg_t was renamed into cti::unpack_arg_t.
* The continuation overload nowreturns result<Args...> rather
than std::tuple<Args...>.
* Add is_ready optimizations to make_exceptional_continuable.
* Makes compiler output much more readable
This is configurateable through CONTINUABLE_WITH_IMMEDIATE_TYPES,
and automatically enabled for debug builds but disabled
for release builds.
* Remove the old continuable-trait.hpp header
* Make the signature of continuable not dependent anymore
on any size of the arguments which fixes the compilation
with forward declared types.
Thanks Rogiel for the correspoding bug report.
