Here's a feature request: can you combine this with a = font-lock rule to display existing regexps in rx syntax? Something like = prettify-symbols-mode, but for regular expressions. You mean a mode so that when the user is looking at the elisp source (if (looking-at "regexp-string") ... he would actually see (if (looking-at (rx translated-expression)) ... ? Could be done, I suppose, but since there is no special syntax for = regexp strings, it would probably either need to rely on a list of = well-known functions with regexp arguments, or second-guess it from = their argument names (like REGEXP or PATTERN). It sounds a bit fragile. I suggest that someone who would like to explore this in detail build a = prototype using xr as the translation engine; its public interface = should be quite sufficient for the task.
