Description

If you enter the following into the GroovyConsole:

import groovy.transform.*

@CompileStatic
class Test {
  List<Integer> elements
  
  public Test( List<Integer> elements ) {
    this.elements = elements
  }
  
  void regularEach() {
    int idx = 0
    elements.each { Integer elem ->
      "$elem:${idx++}"
    }
  }
}

new Test( [1,2,3] )

You get the Error:
