Responsiveness for rendering huge data at the REPL #37
Description
Evaluating range(0, 10000) at the REPL hangs CPO for 5-10 seconds. Evaluating range(0, 100000) hangs it for a very long time, and no output at all is shown while it's busy thinking, nor is there a way to stop the rendering. The stop button isn't active because nothing is "running"...
