I wouldn't call it “abstraction”, a term that I reserve for things that hide their implementation details well. (Litmus test: if you use the abstraction wrong, will the error message show you any implementation details?) Rather, it's boilerplate generation - basically a dynamic counterpart to Lisp macros. Also, I see nothing wrong with the tone of the comment.
