I meant programming style in the sense of using exploratory programming techniques, not in the sense of using particular textual conventions or language features.
I think you're also confusing Lisp with Common Lisp. In a lot of ways (the long names, CLOS, the loop macro) CL is kind of unLispy. The coding style used in those two books (and Viaweb) is closer to the conceptual core of Lisp.
