Failure getCause / exceptionChain ?

[Francois]

Hello guys,

For debugging/logging purpose, I commonly have to find the root cause of
a Failure.
When it is an exception and the failure is composed, I miss something
like "messageChain" but which allows to find the deeper exception of the
composition.

It is rather easy to build the list of Failure in a composed Failure
with a little recursion and then find the first exception (if exists),
but it would be even cooler if it was a built-in method of Failure,
something like:
Failure#exceptionChain : List[Throwable] (deeper first ?)
or
Failure#getCause : Option[Throwable] (only the deepest ?)

What do thing ? How do you log / debug composed Failure caused by
exception ?

Thanks,
