/// @assertion Given a named initializing formal or field parameter (for a
/// primary constructor) with private name `p` in constructor `C`:
/// - If `p` has no corresponding public name `n`, then compile-time error. You
///   can't use a private name for a named parameter unless there is a valid
///   public name that could be used at the call site.
/// - If any other parameter in `C` has declared name `p` or `n`, then
///   compile-time error.
///
/// @description Check that it is a compile-time error if any other parameter in
/// `C` has declared name `p` or `n`. Test initializing formals.
