I just had a thought regarding the Decimal class. If the longer-term intention is to move the class into the core, then would it be sensible to name the class "decimal" (lowercase) rather than "Decimal"? The situation seems similar to the set class, which undergoes a capitalisation change in 2.4 in a similar manner.
