This is great. It makes me think there's something about the simplicity of a line-based interface for both editing and running code that we could still learn from in today's tooling. The interface to BASIC programming had to be simple because the only way you could do anything was by typing at the next line. But due to that very limitation, there was less friction from context switching. I think that's something that hasn't been fully recaptured even by advanced current REPLs.
