Nil: Enhanced Null Check Syntax for Java

Nil allows you to check if an object is null in an if statement. Instead of writing:

if (object != null) { ... }

you would write:

if (object) { ... }

Overview

Experiment & Proof-of-Concept. While functional on Java 21, Nil is not recommended for any use. If you're looking for an alternative syntax, consider other JVM languages. It's not worth torturing the Java Compiler.

This project was inspired by Fluent, which provides a way to compile and test Nil.
