<div class="description long">
<p>Macro to help implement <code>DynC</code> for a concept <code>C</code>. The macro is placed in the
body of the <code>DynC</code> class.</p>
<p>Here <code>DynC</code> is used as a placeholder name to refer to the virtual class
that type-erases for the concept <code>C</code>. The type erasure class is typically
named to match the concept, with a "Dyn" prefix. The type-aware subclass
of the type erasure class is typically named to match the concept with a
"Dyn" prefix and a "Typed" suffix.</p>
<p>The <code>Concept</code> parameter is the concept <code>C</code> for which types are being
type-erased.</p>
<p>The <code>DynConcept</code> parameter is the name of the type-erasure
class <code>DynC</code> which the macro is written within, and which has a pure virtual
interface matching the concept's requirements.</p>
<p>The <code>DynConceptTyped</code>
parameter is the type-aware subclass of <code>DynC</code> which contains the
<code>sus_dyn_concept_typed</code> macro in its body, and the
implementation of the virtual interface that forwards calls through to the
concrete type.</p>
<p>See <a href="sus-boxed-DynConcept.html"><code>DynConcept</code></a> for more on type erasure of
concept-satisfying types, and <a href="sus-boxed-DynConcept.html#examples">DynConcept examples</a> for examples of using the macro.</p>
