<div>
<div>Thank you all for assisting.</div>
<div><br>
</div>
<div>When I tested Mistral I used an older version of Mistral (meaning an older version of yaql).</div>
<div><br>
</div>
<div>I have verified that latest Mistral is working as expected.</div>
<div>I have upgraded the yaql library in yaqluator to 1.1.0 and it is now working as expected.</div>
<div><br>
</div>
<div>Thanks!</div>

<div>It is also worth looking at the upper-constraints.txt. It has 1.1.1 which is the latest release. So it all seems up to date.<br>

</div>
<div>I think the problem is that this external project isn't being updated. Assuming they have not deployed anything that isn't committed, then they are running YAQL 1.0.2 which is almost a year old.<br>

<div>Hello, Moshe </div>

</div>
<div>Tomorrow I discovered <a href="http://yaqluator.com/" target="_blank">yaqluator.com</a> for myself! Thanks for the useful tool!</div>
<div><br>
</div>
<div>But suddenly I was said that the expression </div>
<div>[1,2].join([3], true, [$1, $2]) </div>
<div>evaluated to [[1,3]] on the yaqluator</div>
<div><br>
</div>
<div>A the same time this expression evaluated right when I using raw yaql interpreter.</div>
<div><br>
</div>
<div>Could we fix this issue?</div>
<div><br>
</div>
<div>By the way, don't you want to make yaqluator opensource? If you would transfer yaqluator to Openstack Foundation, then community will be able to fix such kind of bugs</div>
