Dealing with nested association lists is a pain. this let you write your code with a dot notation like jq.
Macros are not only for solving a particular task (serialization, dependency injection, snippets,…) they let you write things the way it makes sense. Like having html-flavored lisps for template, sql-flavored lisp for query,… Lisp code is a tree, and most languages are trees, so you can bring easily their semantic in lisp.
One such example is the let-alist macro in elisp
