your own INIT method which calls this function.
NOTE:
-This can B<not> be used to re-load the dispatch tables for all classes. Use C<reinitialize> for that.
+
+If C<initialize> detects that C<initialize> has already been executed, it will L</uninitialize> and
+clear the MRO cache first.
=item B<uninitialize>
=item B<reinitialize>
-This effectively calls C<uninitialize> followed by C<initialize> the result of which is a reloading of
-B<all> the calculated C3 dispatch tables.
-
-It should be noted that if you have a large class library, this could potentially be a rather costly
-operation.
+This is an alias for L</initialize> above.
