implicit def fromToString[S]: SeedExtractor[S]

The toString method is a good default for almost all types because it is either going to be unique per instance of an object with no overriding definition of it (i.e. not a case class) OR it will be something like a tuple / case class which overrides the definition in such a way that two equal objects will have the same value from calling toString.

Note:

this is low priority to avoid collisions with other shared implicit definitions.
