I'm not sure I would agree, however I'm not familiar enough with Common Lisp's lexical scoping to be absolutely sure (actually, I've never programed in a lexically scoped Common Lisp, just an early IBM-PC interpreter that was dynamic, and that for only a few months).
Common Lisp seems to be missing a number of things I like in Scheme for this sort of thing; my impression is that for understandable reasons the introduction of lexical scoping to mainline Lisp in Common Lisp was done with an eye towards minimal breakage of all that great software that had been developed in the previous 25 years.
