/// @assertion Given a named initializing formal or field parameter (for a
/// primary constructor) with private name `p` in constructor `C`:
/// ...
/// If there is no error then:
/// - The parameter name of the parameter in the constructor is the public name
///   `n`. This means that the parameter has a public name in the constructor's
///   function signature, and arguments for this parameter are given using the
///   public name. All uses of the constructor, outside of its own code, see
///   only the public name.
///
/// @description Check that it is a compile-time error to use a private name `p`
/// as the name of the parameter in the constructor signature.
