[boost] [fusion] tuple missing from sequence models?

Hi, The boost::tuple seems to be missing (intentionally?) from the models of conforming to the forward sequence concept: http://www.boost.org/doc/libs/1_44_0/libs/fusion/doc/html/fusion/sequence/co... Though, the later chapter states it's adapted: http://www.boost.org/doc/libs/1_44_0/libs/fusion/doc/html/fusion/adapted.htm...
