    # RETRO Test File

    This is an example of the literate format
    RETRO uses, which lets us program in a literate style.

    ```
    :test ;
    ```

    That was a test block. It defines a test.

    ~~~
    :word (note)
    	#1 'mald_%n s:format s:put
    	.1.0 drop
    ;

    :hm (idk)
    ~~~

    That's the start of a word.

    These code fences can be placed anywhere.
    ~~~
    	&A $A `a \a |a @a !a
    ;
    ~~~

    Running that gibberish code is not safe for your system, probably.
    You wouldn't wanna do it.
