[Boost-users] bitsets in ITL

I'm evaluating ITL (Interval Template Library which was recently accepted to boost) in order to represent sparse bitsets. In the current implementation the large_bitset class is given as an example with minimal functionality. Are there any plans to develop it into a fully featured bitset and make it a part of boost? It would be nice if it implemented the interface of dynamic_bitset, to ease the migration between dynamic_bitset and large_bitset. Amir
