Hi again,

On the topic of the new array expression functions in QGIS master:

The available list of array expression functions is already quite complete.

Two additional array functions that I would like to see implemented are:

array_reverse(array) (would reverse the order within the array of all 


array_slice(array, start_value,end_value) - this would make it easier to 
extract say a portion of the array, e.g. from the 4th to the 10th element.

Is there any chance that this could be added?
