> To define optional values, Avro has the "union with the null type"
> construction.
> In IDL, this is a rather verbose construct:
> {code}
> union {null, string} optionalName = null;
> {code}
> Wish: add Kotlin style optional types like this:
> {code}
> string? optionalName = null;
> {code}
> The resulting schema should be identical; it's only a syntax change.
> Note: it would be nice (but not required) if the syntax would also work if
> the default value is not null:
> {code}
> string? optionalName = "Jane Doe";
> {code}
