It's not that the Failure is not converted to an exception... it's that the 
Exception
being loaded into the Failure is empty of useful data:

$perl6 -e 'my $c = "Some::Thing"; ::($c).new().perl.say'
Failure.new(exception => X::AdHoc.new(payload => "Failed"), backtrace => 
Backtrace.new)

...something is not putting an X::NoSuchSymbol into the Failure.
