I remember reading about the Lisp-Machines that came out, and some of the d= evelopment tools they had. The "step into / modify [executing] code" debugg= ing seems worlds ahead of anything I've seen on the *nix front (admittedly = only a cursory glance) and substantially ahead of the windows debuggers. (M= S's .NET debugging w/ VS doesn't allow for on-the-fly modification; Borland= 's Delphi debugger allowed you to modify variables / registers on-the-fly, = IIRC.)
