It seems like the only thing you gain is the 'automatic link' back to the caller from the calle and thus an implicit calle.switch_to(caller) upon return from the fiber method. Having to write code to deal with an entirely new type and 'concept' when you could simply add a switch_to() method in addition to a yield() method seems a bit overkill and doubles the amount of code you must maintain and document.

Because asymmetric fiber and symmetric have different 'concepts'
(behaviour) both classes have different interfaces and therefore two
classes exists. Seams to be a valid class design for me.
I don't see the requirement to integrate both interfaces into one class.
Of course you could implement one kind of fiber on behalf of the other.

If you would consider working with me to adopt CMake based modular approach to developing these libraries, I would greatly appreciate it. Otherwise, it it just too difficult to collaborate and do Mac OS X testing for you under the BJam monolithic zip-file based patches.

Hmm - I'm not familiar with cmake. I'll think about it.
