Agery is a set of extensions to Ruby’s Integer class to assist developers in generating arrays of ages. It’s designed to help generate data used when pricing is dependent upon age. Supports neat tricks like: 2.seniors + 1.teenager #=> [65, 65, 13], 1.over_21 #=> [21], and 2.under_18 #=> [17, 17]. See the README for more examples and further introduction.
