Lambdas are Not Functional Programming
Rather than spending time trying tricks with Lambdas, you should:

- Make illegal states unrepresentible in code.
- Make your own data classes immutable and final where possible, use proper immutable collections.
- Use libraries that avoid runtime magic and reflection where pragmatically possible.
