I don't really like the name.  They're not tokens, really.  And I don't know why
it's significant that they were seen (or not seen).  Obviously they were
seen....

Instead of tokens_seen I suggest something like debug_positions and instead of
yields_seen I suggest something like yield_positions.

Done.
