--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The compiler doesn't have to deduce the parameter pack Ts... in that example,
because it is provided explicitly here:
Invoker<std::string, int> invoker;
and so the compiler knows the exact type of std::function<void(Ts...)> here:
invoker.invoke(foo, "a", 1); // ok
without needing to deduce anything.
If Visual Studio compiles it then that seems like a bug in VC++ to me.
