I have dynamic binding script `rcd-template-eval' RCD Template Interpolation System for Emacs https://hyperscope.link/3/7/1/3/3/RCD-Template-Interpolation-System-for-Emacs.html If I call `rcd-template-eval' from dynamic binding script, I guess that works well. If I call it from lexical bound script but don't use the hash to pass it to `rcd-template-eval' that also works. If I wish to pass a hash to function `rcd-template-eval' from lexical bound script, that does not work without `dlet' and that is now broken as `dlet' behaves not any more similar to `let*' I have only 4120 WWW pages currently depending on `dlet', that is interest large enough for function to exist. If there is other solution that would work, I am glad to accept it, except that I cannot and do not want to change dynamically bound script to lexical for reasons previously explained. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
