Fail to populate Vec inside nested before_each

[alex-dukhno]

Hi

I have tried populate Vec with data in nested before_each section, and it failed

describe! outer {

    before_each {
        let mut v = vec![1, 2, 3];
    }

    describe! inner {

        before_each {
            for i in 0..10 {
                v.push(i);
            }
            //if uncommented line below it would pass
            //let b = true;
        }

        it "vector size should be 13" {
            assert_eq!(v.len(), 13);
        }
    }
}

FYI It should work if you put a ; after the closing } of the for. The bug is that the generator silently ignores the expr field of ast::Block of the before and after hooks.
