Thanks; I wasn’t aware of that method’s existence.

Actually, I wasn’t aware that Enumerable existed in the cor; its entry  
in the standard library section on Rubydoc contains no reference to this  
method. Has it been added there since I first looked, in (if I remember  
correctly) version 1.8.4?

Isn’t this the same as Enumerable#any?

This raises one of my few frustrations with ruby. I find ruby far  
easier to work with than Java in general, but the main advantage java  
has is great auto-generated documentation. Both Javadoc and  
autocompletion in IDEs feel superior to what ruby has to offer.
