A key element of this kind of Smalltalk was the idea of turning properties into objects. There is also explicit discussion of the presenter manipulating the view directly. We bet you have hardly thought that becoming a high achiever could be simpler. The variable in the first line of the selection becomes an induction variable, and the programmer can then adjust its bounds.
For example, in the physical world of grocery stories, the 1 and 2 most popular reasons to visit are pharmacy refills and buying milk. This "overhead view" lets a person understand the trip at a higher level. The text field controller then makes a reflective invocation of that method on the reading to make the change.
