# There are a few scenarios where ruby will attempt to implicity
# coerce a given object into a certain type. DummyConfigs can end up
# in some of these scenarios when they're being shipped around in
# callbacks with splats. If method_missing allows these methods to be
# called but continues to return DummyConfig back, Ruby will raise a
# TypeError. Doing the normal thing of raising NoMethodError allows
# DummyConfig to behave normally as its being passed through splats.
