code: def _tuple_deep(v, field, depth, record):
      
      if hasattr(field.value, "__call__"):
          return 0, None, record + (field.value(v),)
  
      for i, f in enumerate(field.value[depth : len(field.value) - 1 :]):
          v = v.get(f)
          if is_list(v):
              return depth + i + 1, v, record
  
      f = field.value.last()
      return 0, None, record + (v.get(f),)
docs: field = {"name":name, "value":["attribute", "path"]}
      r[field.name]=v[field.value], BUT WE MUST DEAL WITH POSSIBLE LIST IN field.value PATH
