I'd add some whitespace and format that docstring in markdown:
~~~
"Takes a screen and a pixel coordinate and returns a map of maps with
pixel colors and adjusted pixel coordinates around the pixel.
Directions are degree numbers from 0 to 315.
in:
* screen (a BufferedImage)
* x (a Number)
* y (a Number)
out: a map of maps, for example,
{direction {:color some-color
:x x
:y y}
...}
where `direction`, `some-color`, `x`, and `y` are all numbers."
~~~
Not only will that be easier to read, but also I suspect that API doc
generator tools will eventually have optional support for treating
docstrings as md and rendering them as html. (Hm, come to think of it, I
opened an issue for codox a little while back regarding this
<https://github.com/weavejester/codox/issues/14>.)
