Quite a contrived misinterpretation, I admit. my: is "my" namespace,
nothing more, nothing less. We don't know what _1 and _2 represent. Both
may be publications. Both may be abstract data structures.

Sure, it does ;) And I generally believe that books are parts of titles

Jeremy's argument thins out to discussing what _1 and _2 are intended to
be, could possibly be, or are desired to be. It's just unproductive.

I see untidiness as far more invidious. Since literals are polymorphic,
it is possible to create a "datatype" for persons and another one for
names, so that literal "Martyn" may represent a person if it occurs in
one context, or it may represent a person's name in another context.
That's what I call invidious...
