AppleScript understands partial paths?

I was under the impression that AppleScript required full paths to files but I’ve just discovered that this isn’t so. This works in OS X 10.2.8:

read file "Users:me:Desktop:Rob's Ten Steps to Rule the World.txt"

Has this always been possible in OS X? :shock:

I remember a while back when folks were writing scripts to open Scripting Dictionaries that you could type in a partial path and the Script Editor would complete it for you. eg., “Users:username:path:to:scriptingAddition” would complete as “HardDriveName:Users:username:path:to:scriptingAddition” when you hit the compile or run button in the script editor.
