Can you modify this program to print out the text read from keyboard a second
time? How about printing a space after every character (grapheme)?
`read-line-from-keyboard` reads keystrokes from the keyboard until you press
the `Enter` (also called `newline`) key, and accumulates them into a _stream_.
This is a good time to skim the section in the Mu reference on
[streams](https://github.com/akkartik/mu/blob/main/mu.md#streams), just to
give yourself a sense of what you can do with them.
