I don't think there's any way for you to avoid using a class
constructor.
Thanks for the explanation. I now tried to use a class and use
a static opIndex. But it seems from a static method you also
cannot access the attributes of a outer class :)
A nested class' outer property (when nested inside another class)
is a class reference, which means we not only require a class
instance of the outer class to reference, but also a class
instance of the nested class to store said class reference to the
other class in.
A static class method (by definition) is invoked without a class
instance.
The two are inherently incompatible.

This seems like an unnecessary limitation...
I can only recommend reading the language specification w.r.t,
nested classes [1] if it seems that way to you, because it is not.
