All of the illustration files have white feathering that doesn’t mesh well with the new background color. Additionally some illustrations have transparent pixels in inappropriate places which significantly changes the perception of the image in dark mode. Dark mode should probably be using similar but different image files. Light mode: Dark mode:
Is your content edit request related to a problem? Please describe. In the syntax-in-function chapter, there is an example that does not compile "out of the box" and uses several new concepts without explaining them. It's the densityTell function that uses readMaybe. Additional context This example uses Just, Nothing and readMaybe which were not yet mentioned at this point in the book and are not explained here. As a beginner, I am also unsure how <- is supposed to work here, as I've only seen used it in list comprehensions in previous chapters. Additionally, on my fresh installation of GHCi 9.6.7, this example does not compile because readMaybe is undefined. This example should contain more detailed explanation of how it works or be moved to later chapter where those concepts are explained.
