>                 Key: GROOVY-8150
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8150
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.5.0-alpha-1, 2.4.10
>            Reporter: Daniil Ovchinnikov
>            Assignee: Daniel Sun
>             Fix For: 3.0

> {code}
> def a
> def b = [1]
> a = b
> println "${a} : ${a.class}" // [1] : class java.util.ArrayList
> (a) = b
> println "${a} : ${a.class}" // 1 : class java.lang.Integer
> ((a)) = b
> println "${a} : ${a.class}" // [1] : class java.util.ArrayList
> {code}
> This is confusing. Here are options:
> 1. {{((a)) = b}} should be failed to parse.
> 2. {{((a)) = b}} should behave like {{(a) = b}}, i.e. number of parentheses should not matter.
> 3. {{((a)) = b}} and {{(a) = b}} should behave like {{a = b}}. This will match the following case also:
> {code}
> class A { def myField }
> def a = new A()
> def b = [1]
> a.myField = b
> assert a.myField == [1]
> (a.myField) = b
> assert a.myField == [1]
> ((a.myField)) = b
> assert a.myField == [1]
> {code}
