Maybe not the best page name, as the distinguishing feature of these things is not just that they are non-canonical but what they imply about the *canonical* morphisms; suggestions for a better page name are welcome. <a href="https://ncatlab.org/nlab/revision/non-canonical+isomorphism/1">v1</a>, <a href="https://ncatlab.org/nlab/show/non-canonical+isomorphism">current</a>

   Format: MarkdownItexIt might be worth mentioning here the situation in homotopy type theory where e.g. univalence follows from the "naïve" formulation $(A \simeq B) \simeq (A = B)$ (this applies more generally to identity systems).
