[GROOVY-10724] Parrot parser incorrectly treats an expression wrapped in parentheses as a cast

• Type: Bug

Description

Trying to compile this code:

def a = ""
(a) in []

results in

/path/to/file/Foo.groovy: 10: unable to resolve class a
 @ line 21, column 9.
           (a) in []
           ^

1 error

Obviously the parentheses are not necessary and the problem goes away if you drop them but it would be good if that code was still allowed like it was in 2.5 or if at least the error wasn't so confusing.
