TDPL code that should work:

Errors out:

Why would the return type of e.next be Throwable if e is an Exception type?

Because e.next is a Throwable reference inherited from Throwable:

class Throwable {
     Throwable next;
}

class Error : Throwable {}
class Exception : Throwable {}

Because collateral exceptions could be both Errors and Exceptions, I don't 
think the sample code can work exactly as written.

Sean's right. And thanks Sean and Walter for implementing the exceptions spec properly, I believe it's very important to the success of D.

Andrej... sounds like another errata entry, please :o).
