If you need an ordered dictionary, such things exist.  The implementation I 
use is at http://www.voidspace.org.uk/python/modules.shtml, but there may be  
one or two other popular ones out there.  You probably shouldn't use them 
unless you have a specific need to.  They will be a lot slower, and extra 
dependencies always complicates distribution.
