Is this the kind of thing you're looking for? That looks nicer than your
proposed syntax in my opinion :)
Forgetting about the assert, you don't like this one-liner?
auto foo = new Foo(Foo.Option(X | Y | Z));
I think we can even make the Foo go away, I think Java does something like
that.
compared to your version (without assert):
Foo foo;
with(foo.Option) foo = new Foo(X | Y | Z);
