Access the latest value

[JJ]

Assign the latest value to a variable, _ for instance, so that you can build on whatever resulted in the last command without having to arrow-up and edit it.

This would be a really nice thing to add. Makes it kind of tricky though since it messes with the type/syntax checkers. You can't use _ as a variable in Go. Might try adding a last val instead or something
