+**Warning:** The comma in `#let (slide,) = utils.slides(s)` is necessary for the unpacking syntax.

 In fact, Touying provides various styles for writing slides. For example, the above example uses first-level and second-level titles to create new slides. However, you can also use the `#slide[..]` format to access more powerful features provided by Touying.
