http://lists.squeakfoundation.org/pipermail/packages/2010-December/004000.html

Name: Kernel-ul.522
Ancestors: Kernel-ul.521

- implemented Fraction >> #negative and ScaledDecimal >> #negative for better performance. These methods don't allocate new objects.
- reimplemented SmallInteger printing methods (printOn:base:*) without String allocation. They are as fast as the previous versions were for base 10.
- reimplemented ScaledDecimal printing. It avoids object allocations and has better performance than the previous version. ScaledDecimals can also be printed without the scale part by using #printFractionAsDecimalOn:.
