In general, predicates in Ruby return an object which can be regarded as
"truthful" or not.

Lately, after reading Douglas Crockford's "JavaScript: The Good Parts," I've
taken to adapting his explanation of "truthy" and "falsy" values to Ruby.  I
like this because it put's Stephen Colbert's notion of "truthiness" into
practice.

In Ruby nil and false are the only "falsy" values, any other object is
"truthy".
