Yes, very relevant. It's the .perl that hangs and even in non-hanging cases it has the potential to perform huge amounts of work, just to throw it all-but-first-score of chars. I see a bunch of other exceptions use .perl and are probably subject to the same issue. I'd say this is another face of some meta ticket for "Errors of Rakudo — The Full Picture"; discussion for which is currently happening on this ticket: https://rt.perl.org/Ticket/Display.html?id=131877#txn-1480778
