The same problem exists with an empty use self::{}; import.
There is no reason for empty self and super imports gives an error when empty crate::{}, some_crate::{} and path::to::a::module::{} imports are perfectly valid. The compiler should of course emit a warning.
If they should be forbidden nonetheless, the error message could be clearer.
It should be noted that the following code if perfectly valid:
mod bar {}
mod foo {
use super::bar::{};
}
use self::bar::{};I obtained such a code with empty super imports with macros.
