[Xotcl] Creating objects from C

When creating XOTcl objects from C, it would be nice to be able to
initialize the new object's clientData prior to any methods being invoked
on the object.

Right now, the only way I can think of to do this is to
1. create the object (which invokes "init", which can't rely on the
ClientData)
2. XOTclSetObjectClientData( XOTclGetObject(), data); // Or the Class
equivalent
3. Invoke some secondary, private "init"-like method that does true
initialization

It would be nice to have two new exported functions:

int XOTclCreateObjectCl (Tcl_Interp* in, Tcl_Obj* name, ClientData data,
struct XOTcl_Class* cl);
int XOTclCreateClassCl (Tcl_Interp* in, Tcl_Obj* name, ClientData data,
struct XOTcl_Class* cl);

That initialize the XOTcl ClientData field prior to invoking "init" so
that "init" could rely on the XOTcl ClientData being valid. This would
make it much easier to construct XOTcl wrappers around C/C++ objects.

Is this reasonable? Is there a better way to accomplish this?
