This is a start on interactive debugging. The means of entry to the interactive debugging mode are BREAKPOINT the native, and a now Ctrl-C will enter the debugging mode as well. (Note: There are several usability questions and questions of what it means to "play nice" as a console program. Many scripts might desire Ctrl-C to exit and not enter the debugger. Both desires are valid, and the decisions about configuration are a separate concern from the groundwork to be able to make the choice. For now, Ctrl-C is chosen to break; and QUIT + HALT are both options for reacting to it.) The commands RESUME, BACKTRACE, and DEBUG are used to work with the interrupted state. These commands are evolving and will be documented on the Trello.

The commands RESUME, BACKTRACE, and DEBUG are used to work with the
interrupted state. These commands are evolving and will be documented
on the Trello. Obvious feature enhancements such as step-in, step-out, and
step-over are on the near-term agenda.
