 Part I Solving Constraints on Object Behavior
   1 Introduction
     1.1 Challenges
         * Constraint Solvers are Non-deterministic ``Magic''
         * Object-oriented Imperative Programming is the Norm
         * Solvers Are Highly Specialized
         * Practical Performance Requires Trade-Offs

 into comparisons and jump bytecodes. The inner loop is jitted,
 the outer isn't, but we get a bridge that executes from the end of the inner loop
 over the jump to the beginning of the inner loop"
