I think it would be very useful. Take, for instance, `cond' - it's a
perfect abstraction and allows you to step into any branch that you
like. Whether it's easy to understand or not, I'd like `pcase' to offer
the same option.

I'm sure that even if I knew all the intricacies of `pcase', I'd still
want an option to "step-in", just like I enjoy this option for `cond`
right now. It's a matter of good tooling, not good documentation.
