3. In the Hierarchy window, select "GameObject"
4. In the Inspector window, under the Test Activator (Script) component, change the TestReciever.RecieveInt method by selecting the field
5. Observe the available methods under TestReciever
Expected result: RecieveLong, RecieveDouble, RecieveDecimal, RecieveByte, RecieveChar, RecieveEnum methods are available
Actual result: only the RecieveInt method is available

The underlying reason is because the UnityEventBase internal method
internal MethodInfo FindMethod(string name, object listener, PersistentListenerMode mode, Type argumentType)
only validates listener method parameter types that match those found in the enum PersistentListenerMode:
void, Object, int, float, string, and bool.Doubles, decimals, bytes, chars, and enums match none of those.
There are also several "register" methods (eg RegisterBoolPersistentListener) that match the allowed types.
