Extracting function pointer from function template is difficult.
In this case, it seems even impossible.
BTW, Boost.Egg: http://p-stade.sourceforge.net/boost/libs/egg/
supports "fusing", which turns function into one taking a FusionSequence.

// \f -> fuse(f)(args)
lazy(lazy(fuse)(bll::_1))(args)

Or, this might be more readable.
// \f -> apply(fuse(f), args)
lazy(apply)(lazy(fuse)(bll::_1), args)
