There is always going to be code that takes more than grep and a glance to understand. Sometimes you won't fully grok it until you've stepped through it line by line, even without "tricks" like metaprogramming. And more often than not the "tricks" make it more concise, less prone to bugs, and easier to understand. It's madness to classify all use of metaprogramming as abuse. Perhaps you need to pour a glass of wine and learn to savor the source code, and to appreciate the power of modern programming languages.
