This is a common problem, we force nobody to use the API ... but the API

My first idea is the have small label object in the array with
__toString method who return the default target label. But during my
last test on that i have some trouble with the serialization (with
igbinary). With this solution with doesn't break anyting.

But i have no idea about the cost of this method in term of memory usage
and cache usage.
