Overview

Insist on correctness.

Example:

data = { "hello" => "world" }
insist { data["hello"] } == "world"

This class aims to work similarly to how rspec’s “should” stuff does, but instead of molesting Object allows you to neatly wrap values with blocks while still checking for expected values.
