native converter questions

Hi,

Suppose you have a class vec2, and a function do_stuff(const Vec2&).
I'd like to have native converters between vec2 and lua tables, so I
could write for example :

  v1=Vec2{1,2}
  do_stuff{x,y}

I specialized luabind::default_converter<Vec2> to achieve this, which 
worked, except that I can not use my vec2 bindings anymore, e.g :

  =v1
  error calling 'print' (No matching overload found, candidates:
  void __tostring(lua_State*,Vec2 const&))
  =v1.x
  No matching overload found, candidates:
  custom [f] <unknown>(Vec2 const&)

(both worked before I wrote the native converter). Does anyone see what
I did wrong? I can give more details if needed.

As an alternative, I thought of writing "light wrappers" instead of
custom converters, but this lead me to 2 problems:

- I have a couple of classes like vec2 above, and a lot of functions
  that take them. I'd need to write wrapper functions (taking
  lua tables) by-hand, for all of them. That's going to be painfull to
  write, review and maintain.

- I could not find a way to simulate a custom constructor allowing to
  write e.g  v1=Vec2{x,y}
  (without touching the original c++ api that is).  The closest I got
  to was adding pseudo class-methods acting like factories:
    v1=Vec2.New{x,y}
  
Is there a better way? Thanks!
