/// @assertion The ability to use `new` or `factory` as a keyword and omitting

/// purely syntactic. The static analysis and meaning of such constructors is
/// identical to the form that uses the class name.
///
/// @description Check that `factory` can be used instead of the class name in
/// declarations of ordinary constructors.
