DebugDescription macro causing “String Interpolation” warnings

Using the DebugDescription macro to display an optional value produces a “String interpolation produces a debug description for an optional value” build warning.

For example:

@DebugDescription
struct MyType: CustomDebugStringConvertible {
    let optionalValue: String?
    public var debugDescription: String {
        "Value: \(optionalValue)"
    }
}

The DebugDescription macro does not allow (it is an error)

"Value: \(String(describing: optionalValue))"

or

"Value: \(optionalValue ?? "nil")"

because “Only references to stored properties are allowed.”

Is there a way to reconcile these?

I have a build log full of these warnings, obscuring real issues.
