Description

import groovy.transform.CompileStatic

abstract class A1 {
    def abstract foo()
}

@CompileStatic
def m() {
    A1 a = { print this } //Groovyc: [Static type checking] - Cannot assign value of type groovy.lang.Closure <java.lang.Void> to variable of type A1
}

Looks like it should work as in dynamic mode.
