This is an initial draft for how an @Memoize annotation could look like.
It currently lacks features such as:
- Thread safety
- Cache invalidation
- Soft/Weak References for a lower memory profile
- Avoiding using a Map entirely for parameterless methods
Ideally at least some of these properties should be configurable using
flags and/or annotation properties (some users might prefer a non
thread safe cache for better performance).
Example Usage:
```java
class Test {
int invocationCount = 0;
public static void main(String[] args) {
Test test = new Test();
System.out.println(test.x(1, 2));
System.out.println(test.x(1, 2));
System.out.println(test.x(1, 3));
System.out.println("Invocation Count: " + test.invocationCount);
}
@lombok.experimental.Memoize
public int x(int y, int z) {
invocationCount++;
return y + z;
}
}
```
