-------------------------------------------------------------

The following use case returns 1 in JS
{code:java}
    @Test
    public void testIncrementOperatorOnNull() throws Exception {
        final JexlEngine jexl = new JexlBuilder().strict(false).create();
        JexlScript script;
        Object result;        script = jexl.createScript("var i = null; ++i");
        result = script.execute(null);
        Assert.assertEquals(1, result);
   }
 {code}
May be we should follow suit?

> It would be nice to allow the C/Javascript/Java for loop:
> for(init-expression; predicate-expression; step-expression) body
> This calls for the prefix/postfix increment/decrement operators.
