This could be replaced with:

Which is actually more efficient.

thanks for the comment Steve. At this late stage in the game do you mind
if I don't include this change in this set. The code line in question is
only in the series because of refactoring. I'm comfortable arguing that
improving efficiency is out of scope ;)

thanks,
Tobin.
