Anyway, maybe the use of the get accessor can be made more readable without effort using tags
struct a{}; struct b{}; typedef coroutine< int( tagged<int, a>, tagged<int,b> > > coro_t; int fn( coro_t::self_t & c) { int x = c.get< a >(); int y = c.get< b >(); c.yield( x +y); ... }
does boost.tuple provide such a facility?
If Boost.Tuple doesn't provides them, Boost.Fusion tuple provides them already.
Maybe if c.get() returns a tuple, boost::tie can be used to improve readability: int x, y; boost::tie(x, y) = c.get(); This doesn't cover the cases when the types are not default constructable but that's a minority of times. I'm going to need this weekend to study the new designs before providing more feedback. -Eugene
