I suspect removing the current key isn't a problem in the current

Been using it quite a lot without any problems :)
But I've changed everything to new the array afterwards as I deleted all the 
keys anyways.

Do you add the ones to be deleted to a dynamic array or do you loop
over all elements afterwards? I expect the first :)
