------------------------------------

    Assignee:     (was: Eric Milles)

> Perform constant folding for basic math calculations in CS
> ----------------------------------------------------------
>
>                 Key: GROOVY-11287
>                 URL: https://issues.apache.org/jira/browse/GROOVY-11287
>             Project: Groovy
>          Issue Type: New Feature
>          Components: performance, Static compilation
>            Reporter: Oscar N
>            Priority: Major
>
> I have the following Groovy code and its Java equivalent:
> {code:groovy}
> @CompileStatic
> final class Main {
>     private static final int ONE = 1
>     static void main(String[] args) {
>         int two = ONE + 1
>         println two
>     }
> }
> {code}
> {code:java}
> public final class JavaMain {
>     private static final int ONE = 1;
>     public static void main(String[] args) {
>         int two = ONE + 1;
>         System.out.println(two);
>     }
> }
> {code}
> In Groovy, it currently compiles to:
> {code}int two = ONE + 1{code}
> In Java, the calculation is done at compile-time and inlined:
> {code}int two = 2{code}
> It would be great if Groovy also did this.
