I was reading this chapter with 3 background thoughts
1/ avoid use/mention bugs
2/ avoid closed world assumption
3/ avoid unique names assumption
This is main concern when things are written in WHERE
but indeed when they are written in FILTER as kind of
syntactic post-processing, then I guess all is fine.

Having the examples in test cases plus bunch of corner
cases in test is what I would like to spend more time..
