Nic Ferrier has posted an interesting proposal to bring namespaces to Emacs Lisp. His ideas seem both reasonable and doable. One of Elisp’s big problems is the lack of a namespace system. We end up with a bunch of nasty looking identifiers such as jcs/fill-buffer-with-zeros or jcs-make-new-entry to avoid identifier conflicts.
Ferrier’s proposal, which you should read, mostly avoids all that without doing much violence to existing code and packages. It’s worth discussing and I hope that the entire Emacs community will read it and contribute ideas and criticism. Having a decent namespace system would make all our lives easier and, at the same time, give Elisp detractors one less thing to complain about.
