The docstring of `pcase' is meant to be "complete", so you can start with that and complain about the missing bits. Don't bother complaining if you're not famailiar with ML-style pattern matching, tho (the docstring is written under the assumption that this much is known). There's a fairly good/extensive example in macroexp.el. Stefan
