Description

The type declaration of the iterator variable in a for-loop seems to be ignored:

List l = ['aaa'] // contains one String
try {
    for (Integer i in l) { // iterator declared Integer (not assignable from String!)
        // GroovyCastException expected in assignment to i in the previous line
        assert false // we should not get this far, expected GroovyCastException
    }
}
catch (org.codehaus.groovy.runtime.typehandling.GroovyCastException e) {
    assert true // expected exception
}

Exception thrown
