Description

// TODO: Fix these use statements
use self::fruits::PEAR as ???
use self::veggies::CUCUMBER as ???

// ... snip

fn main() {
    println!(
        "favorite snacks: {} and {}",
        delicious_snacks::fruit,
        delicious_snacks::veggie
    );
}

At first glance it seems as though the solution would simply be to replace the ??? with respective fruit and veggie;
However after much struggling and leaning on the rust discord community for assistance it was pointed out that the use statement itself should also be changed to pub use. This was not clear in the original problem, as the concept of making an import public is not one I'm accustomed to coming from other languages. The compiler doesn't event suggest this change, making it even more difficult to come to the correct answer without external assistance.

Research direction

Start by reading modules/modules2.rs and the TODO around the use statements. Clarify that the exercise requires public re-exports with pub use as well as the fruit and veggie aliases, then verify the revised instructions make the intended change unambiguous.
