1. I found this name a bit misleading. At first I though that it some king
of iteration through variant types
2. From quick glance on your code it seems that visit_helper class
unnessesarilly parameterized with T0 and T1.
Removing this parameterization (Use member templates instead) should
make your code more simple.
