+**Mike Bayer**, [author of `SQLAlchemy`](https://www.sqlalchemy.org/):
+
+> I can't think of any single tool in my entire programming career that has given me a
+> bigger productivity increase by its introduction. I can now do refactorings in about
+> 1% of the keystrokes that it would have taken me previously when we had no way for
+> code to format itself.
