    55The data used by Pari to compute whether or not an element is a norm can be computed once for each extension `L/K`. The function `pari_rnfnorm_data` computes exactly this, and hopefully in a later version its result can be passed to `is_norm` to avoid recomputing it each time in the case that `K != QQ`. If `K` is `QQ`, there is no need to save any such data -- the only data needed is that of `K.pari_bnf()`, which is used instead, and is already cached by `K`.
