<radical> Going further, shouldn't we start thinking at boost 2.0 which will definitevely let c++03 die its peaceful death and start, on a voluntary effort, move boost component toward C++11. I know we have a fully working Fusion for 0x only. mpl, proto and other strategic infrastructure libraries should benefit from that. Some are a trivial port like Boost.PP and all the TR1 boost library that will just either disappear or forward the C++11 version. </radical>
Joel, you know I'm in favor of this :) but you might want to hold off any serious effort until there are a reasonable number of compilers (say, 2?) supporting variadic templates, decltype and auto, and template aliases -- especially the last. You may find yourself committing designs today that may be dramatically improved with a little extra language support. Andrew
