Detailed Description
A transformation is a function from one datatype to another.
It MUST NOT perform any sideeffects, i.e. it must be morally impossible to observe how often the transformation was actually performed. It MUST NOT touch the provided value, i.e. it is allowed to create new values but not to modify existing values.i This would be an observable sideeffect.
