Nice feature. Note https://github.com/CGAL/cgal/pull/8150#discussion_r1605006265, that could be fixed in this PR.

By the way, it seems the API introduced in #8150 would also allow to use a lambda expression, as argument to allow_move_functor, right?

Would not it be a better example, with a lambda? I am actually note sure... For some readers, lambda functions are kind of magic, whereas they just regular functor classes, defined with a special syntax. I am not completely sure what is the best way to recommend or teach, as an example.

Nice feature. Note #8150 (comment), that could be fixed in this PR.

done

My choice would be to write as-readable-as-possible examples, as long as it does not impact performance

[lrineau]

Jane, this PR was submitted as a draft. You have removed the TODO label. Is it still a draft?
