[Xotcl] Creating objects from C

[Scott Gargash]

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?
