That's an excellent way of thinking about it.  It's essentially a semantic
preprocessor.  Instead of searching for and inserting text, like the C
preprocessor, it searches for and replaces behavior in certain contexts.

Unlike the C preprocessor, though, most aspect-oriented programming
systems don't introduce new symbols to the language.
