Struct Update/ Functional record update syntax error

struct X {
    a : String,
    b : String,
    c : String,
}

impl X {
    fn from_other_X(o: Self) -> Self {
        let c = || {
            X { a: "".into(), ..o }
        };
        c()
    }
}

The closure captures o.b, and o.c. But in MIR we expect to see *o which causes issues
