Is there a nice way of calling a member function on a boost::variant (where I know said member function is implemented by all the types in the variant)?

if the member function has signature: retval func(); then you can call it using the following visitor: // warning: untested struct call_func : static_visitor<retval> { template<class T> result_type operator()(T t) const { return t.func(); } }; You can also pass parameters to the visitor constructor, then forward them to the func().
