Usually I avoid splitting hairs, but since the terminology bikeshed is all about that, let me make a little correction. In julia, there is a data structure called `Expr`, which is what's used internally by the compiler to represent code and is exposed to julia. It's not a list, it's a tree, but the power of being able to access it like any other tree still remains. Of course julia's surface syntax is significantly more complicated than lisp, so macros are more complicated.
