16.1 Analyzing Code at Compile Time

Senior developers and software architects often champion coding standards, and they try to ensure consistent practices are followed in their teams. We can use Groovy’s power to automate code review for smells and poor practices. We’ll see here how to use compile-time metaprogramming to detect smells.
