>             Project: Groovy
>          Issue Type: Improvement
>          Components: Static compilation
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Minor
>             Fix For: 4.0.0-beta-3

> Consider the following:
> {code:groovy}
> @groovy.transform.CompileStatic
> void test(ref) {
>   if (ref === null) {
>     //...
>   }
> }
> {code}
> The null check is written as a call to {{ScriptBytecodeAdapter#compareIdentical}}.  For "ref == null" direct null-comparison bytecode is generated.  There may also be opportunities for constant or reference-to-reference comparisons as well.
