It won't really help either -- it will only change the way TYPEP test
for frozen types are compiled slightly, without any real performance
advantage. Add to that the fact that if/when proper inheritance
sealing is implemented, the FREEZE-TYPE declamation is likely to be
deprecated, I would recommend against using it.
