 when the attached fold_join is compiled, it produces a compile error
 shown in the attached fold_join.compile.

 However, when http://svn.boost.org/svn/boost/sandbox/SOC/2009/fusion/

 in in the include path, it compiles and runs OK producing output:

 v1=(tu<1>(100) tu<1>(b) tu<1>(300.1))
 v2=(tu<2>(100) tu<2>(b) tu<2>(300.1))
 v3=(tu<3>(100) tu<3>(b) tu<3>(300.1))
 fold(vv,state0,join_ftor())=(tu<1>(100) tu<1>(b) tu<1>(300.1) tu<2>(100)
 tu<2>(b) tu<2>(300.1) tu<3>(100) tu<3>(b) tu<3>(300.1))

 The non-variadic fusion should produce the same
 output since no variadic templates are being used.
