Good.
Another possibility is to let D2 accept ? and ! too inside variable
names, so they can become (as in Ruby I think, and something similar is
common in Lisp-like languages too):
array.sort(predicate)
array.sort!(predicate); // void function
array.sorted?(predicate)
Bye,

I never liked that with ruby, I would prefer Michel Fortin's suggestion.
I'm surprised to hear that. I always thought it was very clean and more
generally-useful than things like isBlah (I've frequently run into cases
where the isBlah couldn't be used as it would have resulted in a gibberish
variable name). Only problem I ever saw with it is that it's not a realistic
possibility in D due to ambiguities with other parts of D's syntax.
Maybe it's because typing a ? or ! doesn't fit as good in my hands
compared to other characters, this is using a swedish which requires two
keys to be pressed. I think using the "is" prefix makes it more like
english if you read it, for example, I read "if(array.isSorted)" as "if
array is sorted".
