Maybe it makes sense on some level, perhaps from the implementation POV, but to
me, a language-level user, it makes no sense at all, because a ctor is supposed
to be what initializes the class instance.

Furthermore, a class with a ctor that takes more than zero parameters causes
"auto x = new Class;" to be rejected, because the ctor cannot be called with no
arguments. So to me, this indicates that the ctor will always be called (as
expected); the compiler never says "OK you called new with no parameters, I'll
just default-initialize all your class fields". Since this is the case, it
makes no sense to now suddenly require that all fields be
default-initializable. It has always been the ctor's job to initialize all
fields.

(In fact that's why I chose to use a class instead of a struct, since structs
can be declared without calling any ctors.)
