- Set breakpoints and use the IPython REPL inside a function's scope
- Move the REPL's scope into any imported module
- Hotfix functions being debugged by specifying the correct behavior, instead of just watching them fail
- Works well with text editor integration such as the hydrogen package for the Atom text editor
