Sooo... @carlosantoniodasilva :)

You don't even need to use sort!. Using sort would be enough here.
This applies to the helpers variable just below too.

@dmathieu at least we avoid creating a few extra objects :).

@carlosantoniodasilva: I'm not saying this is bad. I'm saying we create even less extra objects :)

@dmathieu sort! is faster than sort, and avoid creating a shallow copy of the original object
