        Yeah - I was looking at some of the code translations and there
are some register (re)loads that could be removed from the intermediate
stream, and many operations could be done directly within the stored
register variables.  The combination of the two would probably be
helpful... the balance is making sure the translation dosen't become too
much more expensive.
