No, I mean that even for some people unfamiliar with `pcase` syntax, the `pcase` syntax is simpler (more natural?) than the cl-`case` syntax: the incorrect use of `quote` in `cl-case` predates the invention of `pcase` :-) >> > IOW, I don't argue that we shouldn't have `pcase'. >> > I don't see why we shouldn't also have `case' >> > (sans `cl-'), that's all. >> What's the benefit (other than having to learn 2 >> subtly different things instead of just one)? > Simpler, for simple cases. I don't think `case` is objectively simpler. More specifically, I believe that if you're familiar with neither `cl-case` nor `pcase` syntax, it's not easier to learn the `case` syntax than the subset of `pcase` syntax which covers the functionality of `cl-case`. It may even be objectively easier to learn the `pcase` syntax since it doesn't suffer from special cases like when you want to distinguish one of the `nil`, `t`, or `otherwise` values. Stefan
