In the following sections, we'll learn...

• what predicates are, and how to define rules to assign their values
• how associations are easily traversed when defining rules
• combining conditions to define more complex rules
• using references to compare multiple fields or predicates with each other
• passing in arguments from the outside context in which rules are evaluated

Finally, we close with a chapter on Thinking in Dx, learn to apply all the lessons learnt.
