Missing turbofish in nested type params has terse diagnostic

Code

fn main() {
    let _ = bar(Many<i32, Many<(), i32, S, S>, i32, i32>::new());
}

struct Many<A, B, C, D> {
    a: A, b: B, c: C, d: D,
}
impl<A, B, C, D> Many<A, B, C, D> {
    fn new() -> Self { todo!() }
}
fn bar<T>(_: Many<T, T, T, T>) {}

Current output

Desired output

   |                                              ^ expected expression
help: you might have meant to write a "turbofish" `::<>`

Rationale and extra context

The parse error provides no guidance to what the actual problem is.
