Any way to peek at the exception currently being thrown?

Seems obvious for an API:

scope(failure, e) // use exception e

Could also extend to scope success

scope(success, retval) ...

Not sure scope(exit) would work, as only one of the two parameters would 
be valid. But then again, just do scope(success) and scope(failure) at 
the same time.
