So doing what you suggest isn't a sensible thing to do. Lots of Emacs packages rely on cl-lib while supporting older Emacsen as well. There are trade-offs, admittedly, but calling it "not sensible" is like me saying that your choice is ridiculous. My question was specifically to understand which part of the trade-offs made you choose one option over the other. >> That would make you free to use any cl-lib functions and macros >> without having to add matching c--* macros. > The macros are necessitated by, amongst other things, name changes in > functions, some of which have had traditionally approved names for > decades. (I have a copy of the Lisp Machine Manual from the 1980s to > back this up.) Many of your c--* macros are there to choose between the `cl` name or the `cl-lib` name, and every new macro/function you want to use from cl/cl-lib will require another one of those macros. Using cl-lib unconditionally would eliminate this need. Stefan
