Sure, there's stuff that TDPL doesn't describe, but TDPL never described everything (for instance, it doesn't go into a detailed explanation of the various types of is expressions). But that's different from it being incorrect due to language changes, which seems to be what Carl is saying is happening.
What happened is that I unclear what the state of play is; I am not asserting the wrongness of TDPL. Still, I am reassured by your responses.
