DrRacket includes a graphical debugging interface. Clicking on the Debug button will enable debugging mode. Now, hovering your mouse over any parenthesis will show a pink dot. Right-click on it and a context menu will appear with options to set break-points. Use Go, Step etc.. You can observe the stack and variables in the context in the side-pane.
