-<p>Not to be confused with Guile&rsquo;s vector data structure, Sly provides
-dedicated data types for 2D, 3D, and 4D vectors in the mathematical
-sense. Vector procedures are polymorphic, and will work with any
-dimensionality that the operation supports. In some cases, such as
-<code>v+</code>, <code>v-</code>, and <code>v*</code>, scalar values may be passed as
-well.
-</p>
-<p>The <code>&lt;vector2&gt;</code>, <code>&lt;vector3&gt;</code>, and <code>&lt;vector4&gt;</code> type
-descriptors have been exposed for use with Guile&rsquo;s <code>(ice-9
-match)</code> pattern matching module.
