------------------------------------------
Summary: Inconsistency in multiple assignment with single variable
Key: GROOVY-8150
URL: https://issues.apache.org/jira/browse/GROOVY-8150
Project: Groovy
Issue Type: Bug
Affects Versions: 2.4.10, 2.5.0-alpha-1
Reporter: Daniil Ovchinnikov
{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}
