Before Spur Character has always had an instance variable named value. 
Characters are immediate in Spur, so the Character class has no instance 
variables there. If you browse Collections.spur-ul.584.mcz, you'll find 
the following definition:

Magnitude immediateSubclass: #Character
 	instanceVariableNames: ''
 	classVariableNames: 'CharacterTable ClassificationTable DigitValues LetterBits LowercaseBit UppercaseBit'
 	poolDictionaries: ''
 	category: 'Collections-Strings'
