I'm not totally convinced that equality comparison should return a 1-d array, even if it gets implemented. For example, the shape of your example matrices is `(3, 3)`, and the...

PR #267 proposes a `formulaic`-based formula interface for `tabmat`, and Glum [PR #670](https://github.com/Quantco/glum/pull/670) does the same downstream in `glum`. Any comments or suggestions are much appreciated :)

Hey @mayer79, @lorentzenchr, I'd be very interested if the formula interface proposed in #670 would fit your use cases for specifying interactions. You can also find some info in [this...

Good points. It should be efficient. For example, in the case of categegorical-categorical interactions, it never actually expands them to dummies. The new (categorical) variable representing the interaction is created...

It seems that our CI is set up to [publish to PyPI on any GH release](https://github.com/Quantco/tabmat/blob/fbf7755aa48ada1d72dec5d61b7fd9d9f23fdcc6/.github/workflows/build_wheels_release.yml#L3-L6) (including pre-releases), so creating a release with a corresponding alpha/beta/rc tag should be enough...

Hey @matthewwardrop, thanks so much for the response. I really like the idea of `FactorValues` having some metadata about categorical levels, which can be set in `C()` or `encode_contrasts`. Let...
