All the methods that an object can call come from several sources:

its singleton class
its class
all it's parent classes
modules its class includes
modules its parent class's include

One way to find 'detect' is to go to the docs for Array, and when you 
don't see the method listed there, look under the heading Included 
Modules.  In this case, Enumerable is listed, and if you click on that 
link, you will be taken to the Enumerable class and the methods listed 
there include detect.
