I agree with Gemini that the description of inline-letevals was confusing, and I also agree with Eli that the proposed patch was also confusing. :-) So I've taken Eli's suggestion, and the sentence above and added them to the manual, as well as adding a bit more text to explain what it's doing, and where it differs from `let', and pushed to Emacs 28. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
