Sure.   Go ahead.   That kind of documentation is a good thing.
Also, it might make sense to do something like:

  next = this->next
  callback(this)
  this = next

instead of:

  callback(this)
  this = this->next

I see...

Might as well use that existing API.  I dont think you need a full
query.
