-------------------------------------------------
Sure will take a look at it. Just one question after having a glance at the
patch. After doing the pre-checks will be better to do an array copy and then
allow the existing code to do the remaining work? May be your patch is already
doing it and am missing it. Not sure. But just asking?.
> Implement ARRAY_CAT built in function
