_declare_dataframe_name — Record one visible DataFrame binding in the current scope.
_declare_list_name — Record one visible list binding in the current scope.
_declare_tensor_name — Record one visible tensor binding in the current scope.
_declare_value_name — Record one visible value name in the current scope.
_is_dataframe_name — Return whether one visible name is declared as a DataFrame.
_is_identifier_value — Return whether the current token matches one identifier value.
_is_list_name — Return whether one visible name is declared as a list.
_is_operator — Check whether the current token matches an operator.
_is_tensor_name — Return whether one visible name is declared as a tensor.
