<$input> is non-capturing, so even though it contains a $0 capture, its result won't be held by the outermost Match object. Rewrite to <input=$input> or $0=<$input> and you'll see the resulting capture. <pmichaud> m: my $input = '(\d\d\d)'; my $m = 'a 123' ~~ /<input=$input>/; say $m <camelia> rakudo-moar 2c95f7: OUTPUT«｢123｣ input => ｢123｣ 0 => ｢123｣» <pmichaud> m: my $input = '(\d\d\d)'; my $m = 'a 123' ~~ /$0=<$input>/; say $m <camelia> rakudo-moar 2c95f7: OUTPUT«｢123｣ 0 => ｢123｣ 0 => ｢123｣» As far as I know, there's not a way to have a "top-level" capturing interpolation except by using some form of the <foo=...> or $0=<...> syntax. It's always consider a sub-rule capture. Rejecting ticket as not-a-bug. Pm
