Is there a way to avoid `Arg<T>`

[andrewgazelka]

It is super annoying for auto completions to suggest divan get for literally everything.

/// Used by `#[divan::bench(args = ...)]` to enable polymorphism.
pub trait Arg<T> {
    fn get(self) -> T;
}

impl<T> Arg<T> for T {
    #[inline]
    fn get(self) -> T {
        self
    }
}
