However, the variadic Boost.Signals2 implementation still uses Boost.Function for its default SlotFunction and uses Boost.Bind, neither of which provide variadic templates implementations. There should be a working variadic Function implementation in the C++0x BoostCon branch. I haven't updated the documentation yet, but the user-visible changes when using the variadic template implementation are as follows: 1) The "portable syntax" classes like signal0, signal1, etc are gone. 2) The member typedefs like "arg1_type", "arg2_type", etc are gone. They are replaced with a "arg" member template class, so instead of "sig_type::arg1_type" you would do "sig_type::arg<0>::type". For consistency the "arg" member template has also been added to the non-variadic implementation. The same limitations apply to the Function implementation on the branch. It might even have something like the arg member template; can't remember.
