Do you thnk that >macro change the operational semantics of the language, or what?... Lisp and Scheme macros are very much like a compiler in that they can do arbitrary source to target translation. They can't change the characteristics of the underlying target [i.e. the Lisp or Scheme implementation] - but, like a compiler, they can define and translate to the target a new *source* language which has different semantics.
