What is the purpose of finally return in catch clause?
My understanding is that as soon as the return value in the catch clause is about to be evaluated, the control flow pass to the finally clause which having in turn another return, this time the return will be evaluated without passing control back to the catch clause. In this way the only return called at runtime will be the finally return.
