But how would I rewrite my tests, then — which actually want to operate on the captured value?
This is Perl, so there's more than one way to do it, eg
my %sigils =
bang => '!', at => '@', hash => '#',
dollar => '$', percent => '%', caret => '^',
and => '&', star => '*', zero => '0';
my regex line {
^^ :my $s; (\w+) <?{ $s = %sigils{$0} }> \h+ $s (\N*) $s $$
{ make ~$0 => ~$1 }
}
sub parse($_) { map *.<line>.made, m:g/<line>/ }
say parse "star *foo*\nat @bar\nat @baz@";
will generate a sequence of pairs with the key being the name of the sigil and the value the enclosed text.
