             Summary: Hoisted variable is lost when currying lambda
                 Key: JEXL-271
                 URL: https://issues.apache.org/jira/browse/JEXL-271
             Project: Commons JEXL
          Issue Type: Bug
    Affects Versions: 3.1
            Reporter: Dmitri Blinov


I have noticed that when I curry the lambda that contains hoisted variable, then binding to that variable is lost when I call curried lambda. The following test case illustrates the problem

{code}
    @Test
    public void testCurry4() throws Exception {
        JexlEngine jexl = new JexlBuilder().strict(false).create();
        JexlScript base = jexl.createScript("var base = 2; var sum = (x, y, z)->{ base + x + y + z }; var y = sum.curry(1); y(2,3)");
        Object result = base.execute(null);
        Assert.assertEquals(8, result);
    }
{code}

To put it another way, the following script returns {{2}} when it should return {{0}};

{code}var base = 2; var sum = (x, y, z)->{ base + x + y + z }; var y = sum.curry(1); sum(1, 2, 3) - y(2,3){code}
