Does that mean that it's possible that a function definition contains
Does that mean that `symbol-function' will expand them?
Does that mean that if I define a macro, then a function using that
macro, and then change the definition of the macro, the behavior of the
function is undefined?
Sorry for so many questions, but I really want to understand this.
(Also, when that happens, I might send a patch for the manual.)
