I also have a proposal that will provide similar static compilation for {{!in}} as you would get for {{in}} today: [https://github.com/apache/groovy/pull/1621]

> Dear colleagues,
> I've recently updated my projects from 3.0.8 to 3.0.9 and I started getting some GroovyCastExceptions when trying to use *!in* keyword along with CompileStatic annotation:
> {code:groovy}
> org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'true' with class 'java.lang.Boolean' to class 'Xyz'
> {code}
> We realised that it only works on 3.0.9 if we remove the CompileStatic annotation(3.0.8 works with and without).
> Here's an example of how to reproduce the exception:
> {code:groovy}
> import groovy.transform.CompileStatic
> /**
>  *  REMOVE @CompileStatic and the main method runs fine for both versions 3.0.8 and 3.0.9.
>  * 'Cannot cast object \'true\' with class \'java.lang.Boolean\' to class \'MyEnum\''
>  *  @CompileStatic only works with 3.0.8
>  */
> @CompileStatic
> class Groovy309Error {
>     static void main(String[] args) {
>         def myObj = new MyObj(status: MyEnum.A)
>         List<MyObj> items = [myObj]
>         def newItems = items.findAll { it.status !in [MyEnum.B] }
>         println newItems
>     }
> }
> enum MyEnum {
>     A, B
> }
> class MyObj {
>     MyEnum status
> }{code}
>  
> Please, forgive me if I missed something on the bug checklist but I think this ticket belongs here.
> Thank you in advance
