There was also Adpative Programming by Karl Lieberherr at Northeastern University (https://www2.ccs.neu.edu/research/demeter/). He had both a C++ and a Java compiler to implement what he called traversals, features that would span many classes but you could implement in one traversal file. His tools were so powerful that in one of his classes I was able to add synchronization primitives to Java as a class project.
