Right, but can you work with code as if it were data? Can you create
code dynamically like you can create data dynamically? From that point
of view, it is the same.

Compare this to C++: while "code" is integrated in the type system of
the language (for example void(int) is a type) a C++ program can not
create code dynamically. The only thing that can do that is a
compiler, which is not part of the language itself. So that's a
completely different level of separation between code and data.
