Description
Looking at Falcó, Hackbusch, Nouy, Tree-based tensor formats, https://arxiv.org/abs/1810.01262 (#31991), section 3, we may want to implement normed tensor modules.
Currently, our tensor modules are not equipped with a norm:
sage: FiniteRankFreeModule(QQ, 2) 2-dimensional vector space over the Rational Field sage: v = _.an_element() sage: v.norm() AttributeError: 'FiniteRankFreeModule_with_category.element_class' object has no attribute 'norm'
See #30092 (Categories of normed additive monoids/groups, normed modules/rings/fields, ...)
