If $S_q$ is a generative const constructor, and $M$ does not declare any
fields, $C_q$ is also a const constructor.

\LMHash{}%
If $S$ does not declare any generative constructors then the application
does not implicitly induce any forwarding constructors.
In particular, it does not induce a default constructor
(\ref{constructors}).

\commentary{%
The default constructor would have a superinitializer
that attempts to invoke a constructor that does not exist.
Developers would have no way to eliminate this error.%
