Var Resolver api

Hi Miguel,

I have thought about a different api for var resolving:

what about the following, for the first init of a proc:

int
Custom_ResolveVarsInit(
    Tcl_Interp *interp,
    Tcl_Namespace *nsPtr,
    const char * varNames[],
    ClientData * resolveInfos)
{
    /* foreach varname in varNames return ClientData for runtime resolving */
    /* varNames is NULL terminated and contains all the names of the
     * compiled vars, VAR_TEMPORARY are omitted or alternatively, if
     * first character is \0 it is a VAR_TEMPORARY */

    return TCL_OK;
}

for the runtime setting/linking of vars when calling proc afterwards:


int
Custom_ResolveVarLinks(
    Tcl_Interp *interp,
    Tcl_Namespace *nsPtr,
    ClientData * resolveInfos,
    Tcl_Var *varPtrPtr)
{
   /* foreach ClientData in resolveInfos fill in a varPtr
    * (or NULL if not wanted) into varPtrPtr array, which is the variable
    * the varPtr of CompiledVars should be linked to
    */

    retrun TCL_OK;
}

What is your opinion to such an api?
