[Kc] February Meeting Devel:;REPL

[Sterling Hanenkamp]

You also get readline support so you can use arrow keys to go back to a
previous line and edit. You have a configurable prompt. It automatically
dumps the value of the current expression. You can configure tab completion
and a number of other plugins as well. You can also write plugins if you
want to extend the interface for some reason, so you haven't lost anything
other than having to spend some time learning how to write plugins for it.

Cheers,
Sterling
