It's also being used in other parts of Emacs -- I've used it for generic EI= EIO methods (defmethod blah (a b _)) to mean "I have to have a parameter, but am not going to use it", although = it's just a symbol like any other and binds a variable. IIRC it shuts byte compiler warnings u= p about unused variables. ________________________________________ From: Richard Stallman [rms@gnu.org] Sent: 20 December 2015 05:13 To: Phillip Lord Cc: michael_heerdegen@web.de; emacs-devel@gnu.org Subject: Re: The poor state of documentation of pcase like things.
