Yes, I'm pretty sure that's what he intended. It's clearly spelled out in the standard: "the operations plus(a) and minus(a) (where a and b refer to any numbers) are calculated as the operations add('0', a) and subtract('0', b)respectively",
Ah. The great thing about standards is that there are so many of them :-( I was staring at 754-2008, and found nary a mention of "plus" or "minus" operations. But I found the quoted text at: http://speleotrove.com/decimal/daops.html#refplusmin where it also says they "correspond to the prefix minus and plus operators in programming languages". That doesn't leave much wiggle room for a conforming implementation. Next ;-)
