> Backport of GROOVY-7549 caused a regression in temp type inference of local variable assignment.  Consider the following:
> {code:groovy}
>             class Test {
>                 @groovy.transform.ToString(excludes='children')
>                 private static class TreeAttr {
>                     String name
>                     Integer val = 0
>                     List<TreeAttr> children = []
>                 }
>                 void test(Integer count) {
>                     TreeAttr root = new TreeAttr(name:'foo')
>                     List<TreeAttr> collector = root.children
>                     for (name in ['bar','baz']) { // tokens in a path
>                         def item = collector.find { it.name == name }
>                         if (!item) {
>                             item = new TreeAttr(name: name)
> // inferred type of "item" is Object after this point
>                             collector.add(item)
>                         }
>                         collector = item.children
>                         if (count) item.val += count
>                     }
>                 }
>             }
> {code}
> *Note*: This test case works fine for {{3_0_X}} and {{master}}.
