{
    spawn(async move {
        do_something_else_with(
            ^{ self.some_a.clone() },
            ^{ self.some_a.clone() },
            ^{ self.some_a.clone() },
        )
    });
}

Which desugars to

{
    let (a, b, c) = (self.some_a.clone(), self.some_a.clone(), self.some_a.clone());
    
    spawn(async move {
        do_something_else_with(a, b, c)
    });
}

Then have like

'super1: {
    'super2: {
        spawn(async move {
            do_something_else_with(
                ^super1: { self.some_a.clone() },
                ^super1: { self.some_a.clone() },
                ^super1: { self.some_a.clone() },
            )
        });
    }
}

Which desugars to

'super1: {
    let (a, b, c) = (self.some_a.clone(), self.some_a.clone(), self.some_a.clone());

    'super2: {
        spawn(async move {
            do_something_else_with(a, b, c)
        });
    }
}

And finally, the harder to read

'super1: {
    'super2: {
        spawn(async move {
            do_something_else_with(
                ^^{ self.some_a.clone() },
                ^^{ self.some_a.clone() },
                ^^{ self.some_a.clone() },
            )
        });
    }
}

Which desugars to

'super1: {
    let (a, b, c) = (self.some_a.clone(), self.some_a.clone(), self.some_a.clone());

    'super2: {
        spawn(async move {
            do_something_else_with(a, b, c)
        });
    }
}
