I just tried this:

class A
{
protected:
    this() { printf( "ctor\n" ); }
}

int main()
{
    A a = new A();
}

And it compiled and, when run, printed: "ctor."  Is the "protected" keyword not working correctly or is there some rule that class constructors are inherently public?

Attributes are apparently applied at the module-level, rather than the class-level.

That is not true in this situation.  Constructors are always public.

Hm.  So how would I go about creating a singleton or other class that has special construction requirements?

I'm not exactly sure what you mean by special construction requirements.  There was a whole discussion on singletons before, so you might what to look at that (using module-level or static members were suggested). Search for singletons.

Thanks.  As for special construction requirements, I think that could all be handled by overloading "new."  Just thinking out loud.
