/// @assertion The ability to use `new` or `factory` as a keyword and omitting
/// the class name in declarations of ordinary (non-primary) constructors is
/// purely syntactic. The static analysis and meaning of such constructors is
/// identical to the form that uses the class name.
///
/// @description Check that it is a syntax error to declare a `factory new`
/// constructor.
