+<p>
+  Gleam has the <code>==</code> and <code>!=</code> operators for checking
+  equality.
+</p>
+<p>
+  The operators can be used with values of any type, but both sides of the
+  operator must be of the same type.
+</p>
+<p>
+  Equality is checked <em>structurally</em>, meaning that two values are equal
+  if they have the same structure rather than if they are at the same memory
+  location.
+</p>
