	Well, in my case, I am taking values from a form, cleaning them up 
(removing punctuation from phone numbers, etc.), and then updating a 
database with these 'processed' values. I changed one of my methods from 
dtml-let to REQUEST.set, and it worked perfectly while becoming much, 
much cleaner. So while the two may not be equivalent, they both do what 
I need, and REQUEST.set is far superior for this.
