   @ekaitz_zarraga I'd love such a feature.

   Currently the compiler warns about unused functions and arguments (i.e. dead code), but it doesn't warn about unused imports.

     @ekaitz_zarraga Yes, please 🙂

     I've been wanting this since forever.

     @ekaitz_zarraga Well, the compiler is already doing some sort of check for all the symbols in the file to see what's being used and what isn't (in the case of `unused-variable` and `unused-toplevel`). So adding the new warning would be a matter of determining all the symbols brought in by each import, comparing that against the symbols used in the code, and then warning about any import whose symbol list had no matches in the current file.

     But don't forget about shadowing!
