That's a good question.

My main criterion is "A C++ implementation of this algorithm will not crash". 
So no getting properties from null pointers, for example, or putting the
iterator in a state that the spec doesn't expect it to be in.

Past that, I don't really care about _sanity_ in this case, because as you
point out there won't be any no matter what.
