+<p>
+  The record update syntax can be used to create a new record from an existing
+  one of the same type, but with some fields changed.
+</p>
+<p>
+  The accessor syntax can only be used for fields that are in the same position
+  and have the same type for all variants of the custom type.
+</p>
+<p>
+  Gleam is an immutable language, so using the record update syntax does not
+  mutate or otherwise change the original record.
