It is possible to get callbacks in ECL. I have implemented that in my

(Of course SML does have its weaknesses, but by comparison, a
 discussion of C++'s strengths and flaws always sounds like an
 argument about whether one should face north or east when one
 is sacrificing one's goat to the rain god.)         -- Thant Tessman
