I personally favor this approach whenever possible, it fits 
nicely with UFCS and allows to keep data type signature clean 
from unrelated stuff. My guideline is "If something simply 
operates on an aggregate, make it a free function. If it requires 
some knowledge about private aggregate state and/or is something 
done by aggregate, make it a method".
