I don't know what to say, since it sounds like the "appetite comes
with eating".  We never talked about PT_POS before.  Is the plan to
make any popular position a struct?  Like GPT, for example?  What
about BEGV and ZV?

IOW, I don't understand the goal here.  I think I did understand when
we were talking about accessing characters by buffer positions, and
the bugs related to incorrect usage there, but now it sounds like the
plot thickens?
