> Affects Versions: 2.3.0-beta-1
> Reporter: Maxim Medvedev

> 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

> Of course, these checks are not applicable to reassigned parameters, but in
> most cases closure parameters are not reassigned.
