If that happens on master, then both cond* and the conversion need to be perfect before the file can be committed. On a branch, things can be a lot less constrained. What I want to do early on in cond* development is convert lisp/emacs-lisp/macroexp.el from pcase to cond*. Currently, pcase.el is dependent upon macroexp.el and macroexp.el is dependent upon pcase.el. This leads to an unlovely artifice in the bootstrapping file, loadup.el, and this has caused me grief in another branch I'm working on. cond* has no dependency on macroexp.el, so could simply be loaded as the fourth file, after debug-early.el, byte-run.el, backquote.el. Having macroexp.el loaded as the fifth file (rather than the 17th, as it currently is) would simplify the initial loadup appreciably. No doubt Eli will have something to say about this idea. ;-) > Nothing should really stop development if this lives on master, or a > branch. There are advantages to the branch, as well as advantages to having it on master. -- Alan Mackenzie (Nuremberg, Germany).
