Views in k/q. A view is like a variable whose value is determined by a dependency expression. / any time c changes, f will be updated f::32+1.8 c / temp (F) from temp (C) / any time m or x or b change, y will be updated y::b m*x Lots of conditional logic falls away when dependent relationships can be described this way.
K's coupling of data and user interface elements. All data can have a gui widget type in its metadata. The benefit was: * If you changed the widget then the data changed. * If you changed the data then the widget changed. The layout of the data implied the layout of the widgets. Using that version of k was the only time that I ever willingly did UI development.
P.S: don't take this to mean i hate on racket, i'm just complaining about the default state of racket/gui, there have been attempts to improve it by 3rd party libraries(https://docs.racket-lang.org/gui-easy/index.html).
