    I think I am one of the persons who fail to distinguish token from occurrence.
In point of fact, I considered them two entirely different things and never
connected them (so possibly may not actually have confused them [?]).  However, I
could not follow some of your points and wonder whether you'd please elucidate
with examples the difference between a letter type and a letter token, and how
both relate to occurrences of a particular letter in a word type and in a word
supposing what I'm asking makes sense.
