From: Jesse Perla 2) Dynamic Bounded Types: Right now the static bounds are associated globally with a type, and the dynamic bounds are associated with an instance of a type. Since many use cases involve setting dynamic sets and then creating instances, it is crucial that this type of set is implemented. See Robert's rough notes in: http://lists.boost.org/boost-users/2008/12/42959.php
Yes, this might be added in the future to the library itself. But first I want to become confident this is what actually users need and that this solution is general enough. Therefore, I'd be grateful if you (and other possible users) could test the provided code and say how well is it fulfilling the requirements. ;-)
This too is already solved if any predicate is acceptable: just use a predicate functor that forwards via a pointer or reference to another global predicate. Or (somewhat less efficient but easier) use the dynamic boost::function predicate that is already included and boost::bind/lambda/phoenix to a method on this global object.
