Agreed when it is intentional, but not when it is a missing or partially 
implemented feature. For example, the standard has

   template <class F, class ...Args> explicit thread(F&& f, Args&&... args);

Boost.Thread has not yet implemented this function completely. I see 
this as a limitation. The limitation could be resolved or not in a 
portable way, but at least on C++11 compilers the feature should be 
implemented in a near future. We plan to do it, but as you know we can 
not do everything at once ;-). Hopping this clarifies my point.

Sorry for been out of topic,
