This was discussed for PR #1516. See in particular [its conclusion](https://github.com/UniMath/UniMath/pull/1516#discussion_r898908818).
This issue ought to be resolved before generalizing whiskere…

Currently in a tensor product of crystals, we search through all elements and filter. However if given a highest weight element in a tensor product `a (x) b`, then `b` must be highest weight. This m…

DisCoPy is a library for applied category theory, but it has no explicit definition of categories. I propose to create a class `Category` which is just a named tuple for a par of Python types `ob` and…

We need an implementation of symmetric categories, see [here](https://github.com/toumix/thesis/blob/main/discopy/symmetric.py).
For now, the `Swap` class is in `monoidal`, it needs to go to its own `…

Given an equivalence `F : C ⥤ D` of categories, and a monoidal structure on `C`, there is a (essentially unique?) monoidal structure on `D` making `F` a monoidal functor.
