Well, here the discussion can go both ways! Because in a way it makes sense that every file `provide' its stuff, and every other file that wants to use it `require' it. Update 1, elint is correctly seeing defuns in lexical let-closures, and there is no need to use `declare-function' for it do that as was incorrectly theorized the day before. This is interesting because the byte-compiler does not see those so there declare-function is needed. Update 2, elint cannot see variables in `pcase-let' when the variables are defined using the `(,a ,b ,c) syntax - warning BTW, if that looks like a list with a bunch of items being evaluated, that isn't the case, here, it is a syntax used for special purposes by pcase-let. pcase-let was introduced in Emacs 28.1, probably elint has not been brought up to date on it. -- underground experts united https://dataswamp.org/~incal
