This works for restartable (purely functional) code. It also works for single stepping.
It's not so simple for code with side effects, breaking into the debugger after hitting an error. But perhaps that issue should be dealt with through documentation, rather than code, except for the trivial issues that are always going to be present (even in "pure" code).
