There is an indentation issue in src/sage/combinat/species/partition_species.py line 145.

       """
        return super().__classcall__(cls, *args, **kwds)

[dcoudert]

The last commit breaks doctests.
Actually, we originally have

    def __classcall__(cls, *args, **kwds):
        """
        EXAMPLES::

            sage: P = species.PartitionSpecies(); P
            Partition species
       """
        return super().__classcall__(cls, *args, **kwds)

So I wrongly pointed to the line with return while it's the line with """ that is not properly indented.
