I think this is because
f is a is a boost::function object. You'e trying to pass a functor
object to a function that takes a std::string& argument, and that's
what the error is saying that it can't coerce f to a std::string type.

Instead of using a boost::function<...> object try passing it directly
to the expression, like as follows.

for_each( v2.begin(), v2.end(), bind(
insert_func, var(str_con), bind(&test_str::str, Arg)));

the boost::lambda::bind function returns a lambda functor.
