>                 URL: https://issues.apache.org/jira/browse/GROOVY-6603
>             Project: Groovy
>          Issue Type: Improvement
>          Components: Static Type Checker
>    Affects Versions: 2.3.0-beta-1
>            Reporter: Maxim Medvedev
>            Assignee: Eric Milles
>            Priority: Major
>
> Static type checker should check calls to closure parameters with provided @ClosureParams information:
> {code}
> @CompileStatic
> void foo(@ClosureParams(value = FromString, options = "java.lang.Number") 
>          Closure cl) { 
>     cl("a") //Compilation should fail here
> }
> {code}
> Of course, these checks are not applicable to reassigned parameters, but in most cases closure parameters are not reassigned.
