Are there contemporary programming languages that do NOT have the ability to import functions or values or whatever from other files? Are there situations in which that would be a feature? (lemmy.ml)

Deno is an example of a language runtime (based on Javascript+Typescript) that's been built with capabilities in mind. By default, programs aren't allowed to touch the filesystem or network (except to allow static imports to run; fallible dynamic import calls that could be used to determine something about the filesystem or network are restricted like other IO). Programs can start up worker threads that have further permission restrictions than the main program.
