max\min against arrays #351

Hi,

Sorry maybe my brain still thinks the other way but how would you solve this problem:
bazaarvoice/jolt#700

I cant think of a way without having to create custom recursive max\min as in:

def max_array(array)

if(size($array)==0)
null
else if(size($array)==1)
$array[0]

else max($array[0],max_array($array[1:]))

vs

{

"minPrice": min([for(.prices).price])
"minPrice": max([for(.prices).price])

}

Thanks
