Good Morning people... Sorry by my very very bad English .. I'm Brazilian and new with kotlin... but go try ... I see many examples in the web and all of them uses 'VAL' for create properties ... Then I think: When update an registry ... how to make? If 'Val' is equivalent to 'Final' of the Java ...

By default final or val is a thread safe. You you will expect no one can change the value after he created. In kotlin, you should use val as long as possible.
