+=head2 Class Creation at Compile Time
+
+C<Class::Struct> can create your class at compile time.  The main reason
+for doing this is obvious, so your class acts like every other class in
+Perl.  Creating your class at compile time will make the order of events
+similar to using any other class ( or Perl module ).
+
+There is no significant speed gain between compile time and run time
+class creation, there is just a new, more standard order of events.
