WhyNot?

not_empty?, not_blank?, … why_not? Tired of writing !array.empty? Ruby is ledgible and should be more ledgible. Ruby is terse and should be terser. A predicate method is one that returns a boolean and ends in a question mark. This simple library adds corresponding negation methods for all Ruby predicate methods.
