Stepping isn't so easy.
Very true.
Few Lisp's support stepping line-by-line.
All ANSI CL support stepping form by form which is a more relevant measure for lisp than line-by-line: http://www.lispworks.com/documentation/HyperSpec/Body/m_step.htm#step But in 20 years of Lisp programming darned if I've ever been able to make this give me any useful information. Reading the spec, I notice that implementations are permitted to treat this essentially as just execute the form. That's never happened in my experience, but I've never clearly understood on any implementation exactly what it is I am looking at.
