Yes, but this arrow should not point right, but up (which was the
thought underlying Smalltalk's choice). Maybe finally use unicode "↑".
Or more conservatively, "^".
I still think a symbol is better than keyword, because there is no
single common word that applies across contexts this may be applied in,
except possibly "yield", that already means something else in Java
(Thread.yield), and several something else's in other languages.
