If you are using Typst to edit a document and you "refer to" later or earlier sections – it is definitely lifesaving if you move text around, helps keep track of repetitions, causes errors if you remove the section and helps the reader avoid scrolling/searching through the text. It also adds polish.

Definitely a must if you're e.g. writing a thesis.

Example:

== Section 1 <banana>

== Section 2

#link(<banana>)[In an earlier section], we elaborated on...

#typst

@n0toose I often also like the form: `In @my-section-anchor above` which renders to "In Section 3 above" with a link.
