+L<MooseX::Role::Parameterized> in order to simplify reusing sugar
+from other modules that use C<Moose::Exporter>. This function is
+used, for example, to select the metaclass to bind to functions
+that are exported using the C<with_meta> option.
+
+This function will receive one parameter: the class name into which
+the sugar is being exported. The default implementation is:
+
+    sub { Class::MOP::class_of(shift) }
+
+Accordingly, this function is expected to return a metaclass.
