And as a follow up: http://irclog.perlgeek.de/perl6/2015-11-17#i_11554347 vendethiel but perhaps someone who knows the rules of CATCH a bit more than I do can confirm what psch++ said http://irclog.perlgeek.de/perl6/2015-11-17#i_11554028 jnthn vendethiel: Believe so. It's $_ inside of CATCH 'cus you want to be able to smartmatch on it
