<h3 class="section">3.4 Cacheing and Dispatch Functions</h3>
<p><code>SB-PCL::CACHING</code> functions simply cache effective methods as a
function of argument wrappers, while <code>SB-PCL::DISPATCH</code> functions
have code that computes the actual dispatch. <code>SB-PCL::CHECKING</code>
functions have a cache, but on cache misses will recompute whether or
not to generate a <code>SB-PCL::CACHING</code> or <code>SB-PCL::DISPATCH</code>
function.
</p>
<p>(FIXME: I’m actually not certain about the above paragraph. Read the
code again and see if it makes any more sense.)
