- Yet another window-based improvement: the possibility to evaluate a
- lambda expression by selecting it with the mouse and then using the app-
- ropriate menu option. Smalltalk V/PM has that feature for OOP. I just
- never really got round to remebemring the appropriate PC Scheme Edwin
- commands for evaluating a single lambda expression and returning to break
- mode.
- A question: does Schematik do that, and does it run on SPARCs under
- X or OpenWindows?
