I tried that, and it is not as nice as one would think. It is not
highlighted as an operator for one.
Smalltalk does not allow a leading underscore for variable names because
of this usage of underscore. In many other languages there is a
convention of using leading underscore to mean something, like to
supress warning of unused variables. Many people including me like the
visual cue it provides.
