Using Chainer with varying Functors

[Nobody/Anonymous]

I'd like to be able to chain together these Functors:

Loki::Functor<void, LOKI_TYPELIST_1(int)> c1(pDog, &Dog::RollOver);
Loki::Functor<void, LOKI_TYPELIST_1(std::string)> c2(pDog, &Dog::Listen);

but when I try

Loki::Functor<void, LOKI_TYPELIST_1(std::string)> cmd34(Loki::Chainer<foo, foo> (c1, c2));

I can't make the compiler happy.  Is this possible?
