Enum values can have a value, but I'm afraid the getting the int value is slower than using an int directly. public static final int a = Intege...

In Ruby, you can call Enumerable#any? on a enumerable object to see if any of its elements satisfies the predicate you pass in the block. Like so: lst.any?{|e| pred(e) } In Python, there's an any function that does something similar, but on a list of booleans. Of course, for a reasonably-sized list, I'd just do: any(map(pred,lst)) ...
