+B<NOTE:> The B<StorableFile> I/O option is not supported,
+this is because it does not mix well with options who also
+have a C<thaw> and C<freeze> methods like this. It is possible
+to probably work around this issue, but I don't currently
+have the need for it. If you need this supported, talk to me
+and I will see what I can do.
