Julien Edmond René Harbulot added the comment:
Consider how easy in the REPL it is to hit `up arrow` and then append code to
the previously entered command, compared to having to move the cursor back in
the command to edit it somewhere in the middle.
Simulated REPL session:
```
dir.iterdir
New submission from Julien Edmond René Harbulot :
I work with python in the REPL or jupyter notebooks for my data science work
and often find myself needing to explore data structures or directories on disk.
So I'll access these data structure in a linear "go-forward" fashion
