In my previous post, I forgot to mention that the code sample
I gave only gives FutureWarnings because of the literal hex
constant used.  In your real application, you will not need
to do this (because you will be using long(somestring,16),
similar to the third test line in my example).  So the chances
are that you will not encounter any FutureWarnings using this
method.
