Yes, thanks Fred.  That is exactly what I was looking for.  I had tried 
s[1-] and s[1...] but I had forgotten that it was the colon.

Here is the script I ended up with... I'd like to make some additions to 
it, so that if I specify an overloaded setter method it calls the "true" 
setter method (the one that actually modifies the property), but it's 
been a long day and I'm going to go home now.
