Ordinary reference as value ?

[witwolf]

Now, gin config support configurable reference, macro , basic type (str, bool, number) or nested of them as value . It would be great if we can refer to local variable (module, class ,function)

  def testLocalVariableReference(self):
    config_str = """
          configurable2.non_kwarg = a
    """
    config.parse_config(config_str)

    a = 1
    instance, _ = configurable2()  # pylint: disable=no-value-for-parameter
    self.assertEqual(instance, a)

    a = 2
    instance, _ = configurable2()  # pylint: disable=no-value-for-parameter
    self.assertEqual(instance, a)

  def testUnregisteredFunction(self):
    config_str = """
             configurable2.non_kwarg = numpy.abs
    """
    config.parse_config(config_str)
    import numpy
    instance, _ = configurable2()  # pylint: disable=no-value-for-parameter
    self.assertEqual(instance, numpy.abs)

without this , we make all function that may refer to to be configurable explicited by gin.external_configurable , it seems not reasonable .
