>                 URL: https://issues.apache.org/jira/browse/GROOVY-9652
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.5.13
>            Reporter: Eric Milles
>            Priority: Major
>
> This started failing with Groovy 2.5.13:
> {code:groovy}
> class Node {
>   String name, text
> }
> class Root implements Iterable<Node> {
>   @Override
>   Iterator<Node> iterator() {
>     return [
>       new Node(name: 'term', text: 'foo'),
>       new Node(name: 'dash', text: '-'  ),
>       new Node(name: 'term', text: 'bar')
>     ].iterator()
>   }
> }
> @groovy.transform.CompileStatic
> void test() {
>   Root root = new Root()
>   root[0].with {
>     assert name == 'term'
>     assert text == 'foo'
>   }
>   root[1].with {
>     assert name == 'dash'
>     assert text == '-' // GroovyCastException: Cannot cast object 'script@b91d8c4' with class 'script' to class 'bugs.Node'
>   }
> }
> test()
> {code}
> I noticed some changes in {{BinaryExpressionTransformer#tryOptimizeCharComparison}} that may be relevant.
