[luabind] default_converter and luabind assignment

[<Aru...@hi...>]

Hi,
I want to add support to a user type in luabind, so that I can assign c++ variables of the type to lua variables like so:

struct UserType{..};

//and then do

UserType u;
luabind::globals(L)["UserTypeList"]["a"] = u; //equivalent to saying UserTypeList.a = u  in Lua.


I registered the class type via luabind::class_ and specialized the default_converter for the type :

module(L)[ class_< UserType>("_ UserType")];

namespace luabind{
     template<>
struct  default_converter< UserType> : native_converter_base< UserType> {
     //define compute_score, to and from functions.
};
}


But when I actually do the assignment, the converter code doesn't get called. I'm expecting the 'to' function in the converter to get called, since I'm assigning a custom  type to a lua object, which doesn't happen.
Is this the correct way to do this. Please let me know if you find any issues with this setup.

Thanks arun.
