The word “properly” is not only working hard here, but perhaps pointing to deeper concepts.

In particular, it implies a coherent design around scope and extent. And, much more indirectly, it points to time. EVAL-WHEN has finally made a bit of a stir outside Lisp.

Does this imply that lambda expressions in Haskell and ML don't have a "coherent design around scope and extent"? This is quite a claim, to be honest....

No, it doesn’t imply that. There are plenty of more popular languages that don’t though.
