          to the alternate name given as the "name"
          argument of the synonym; in this way, the usual step of redefining
          the mapping of the :class:`_schema.Column`
          to be under a different name is
          unnecessary. This is usually intended to be used when a
          :class:`_schema.Column`
          is to be replaced with an attribute that also uses a
          descriptor, that is, in conjunction with the
          :paramref:`.synonym.descriptor` parameter::

            my_table = Table(
                "my_table", metadata,
                Column('id', Integer, primary_key=True),
                Column('job_status', String(50))
            )

            class MyClass(object):
                @property
                def _job_status_descriptor(self):
                    return "Status: %s" % self._job_status


            mapper(
                MyClass, my_table, properties={
                    "job_status": synonym(
                        "_job_status", map_column=True,
                        descriptor=MyClass._job_status_descriptor)
                }
            )

          Above, the attribute named ``_job_status`` is automatically
          mapped to the ``job_status`` column::

            >>> j1 = MyClass()
            >>> j1._job_status = "employed"
            >>> j1.job_status
            Status: employed

          When using Declarative, in order to provide a descriptor in
          conjunction with a synonym, use the
          :func:`sqlalchemy.ext.declarative.synonym_for` helper.  However,
          note that the :ref:`hybrid properties <mapper_hybrids>` feature
          should usually be preferred, particularly when redefining attribute
          behavior.

            For the use case of providing an attribute which redefines both
            Python-level and SQL-expression level behavior of an attribute,
            please refer to the Hybrid attribute introduced at
            :ref:`mapper_hybrids` for a more effective technique.

        Allows any Python descriptor to behave like a SQL-enabled
        attribute when used at the class level in queries, allowing
        redefinition of expression operator behavior.

        In the example below we redefine :meth:`.PropComparator.operate`
        to wrap both sides of an expression in ``func.lower()`` to produce
        case-insensitive comparison::

            from sqlalchemy.orm import comparable_property

            from sqlalchemy.sql import func
            from sqlalchemy import Integer, String, Column

                def operate(self, op, other):
                    return op(
                        func.lower(self.__clause_element__()),
                        func.lower(other)
                    )

            Base = declarative_base()

            class SearchWord(Base):
                __tablename__ = 'search_word'
                id = Column(Integer, primary_key=True)
                word = Column(String)

                            )


        A mapping like the above allows the ``word_insensitive`` attribute
        to render an expression like::

            >>> print(SearchWord.word_insensitive == "Trucks")
            lower(search_word.word) = lower(:lower_1)

          descriptor or property to layer comparison behavior on top of.

          mapped class if left blank in a ``properties`` declaration.
