I think you can do this with a :default pseudo-rule
<http://search.cpan.org/%7Ejkegl/Marpa-R2-2.090000/pod/Scanless/DSL.pod#Default_pseudo-rules>.
Just have the default action be to die. Not quite the same as what you
are asking, but a reasonable substitute I hope.

Would it be possible to add a flag to new(), something like
new(missing_action => 'die')? It could default to 'ignore'.
I'm thinking of forcing an exception if the search fails for a closure
named in an action.
