A number others also expressed confusion about it, what > the syntax means and how to interpret it. I found it hard to interpret some specific pcase constructs despite having read its documentation. It did not come naturally. However, with more experience I have learned to understand them. It still requires an annoying amount concentration, but I can do it. I still think pcase is inconvenient in some of its uses -- once one gets beyond the basic kinds of patterns. I do not advocate removing or changing pcase itself. Too much code depends on it. I do hope to discourage its use inside Emacs in favor of cond*. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
