Is Self Chaining possible in Queueable Interface?

#QueueableInterface allows Chaining Jobs.

For re-sending the failed records during a web service callout from SFDC to SAP, today I was just wondering if Self-Chaining is possible.

I wrote the below piece of code:

System.enqueueJob(new SameClassImplementingQueueable(listObject)) ;

And it compiled successfully. (Y)

So I believe the compiler allows us to perform self-chaining as well. Now I need to check what happens at the runtime.

The only restriction I see for implementing Queueable Interface is this: "The maximum number of jobs in the chain (maximum stack depth) is two, which means you can add only one job from an executing job".

I believe I am within the Salesforce limits.  :P  ;)

P.S: If it happens, I need to see how it behaves in its Test Class.  :D
