Code and data interact in different ways at different levels, and the distinction isn’t always clear-cut. In some languages it’s very blurry indeed (LISP, shell scripts, machine code). Object-oriented languages have specific ways code and data combine, functional languages have others. It sounded from some of your earlier messages* like you may not be used to object-oriented languages (or maybe just used to very rigid ones like C++ or Java), so some things you interpreted as unclear might just reflect a different way of thinking than you’re used to.
