Given:
fail with configurable behavior
no fatal to make fail just warn
use fatal to make fail throw exceptions
A question came up on #perl6 for the following code:
no fatal;
class Foo {
use fatal;
method bar() { fail; }

no fatal to make fail just warn
I thought it wouldn't warn, but instead silently return undef (an
unthrown exception).

Juerd is right here, it doesn't warn. Instead of dieing, it returns
an undef with some helpful diagnostic information (an unthrown
exception as Larry has

Oh, just to avoid further confusion: In the baz() called under fatal,
it will only turn undefs that were generated by fail calls into
exceptions. Other sorts of undefs will be returned as ordinary
undefs.
Ok, so let me try to get my head
