[boost] Boost libraries for 'TR2'

Hi, just out of curiosity, which Boost libraries could we expect to be proposed for the TR2 (or whatever the new C++ run for new libraries will be called)? Who is working on a concrete proposal? Which libraries would you like to be proposed? I would like myself to see between others: Accumulators, Any, Asio, DynamicBitset, Filesystem, Format, Fusion, Interprocess, Intrusive, Mpl, Optional, PointerContainer, ProgramOptions, Proto, Range, Signals, Thread (shared locks), Units and Variant. Best, Vicente
