That's what I've written a library to fix - it makes it quick and easy to bind C++ api's to make them callable from a dynamic language. Not only can you bind a C++ function with 1 line of code, but if that function returns an object, the returned object's member functions are callable on its scripted instance:

Currently there is only an Io backend, but the library is designed so that the same C++ bindings can be used with multiple different backend languages. It's like Boost::Python on steroids.
