There is actually a third issue in that spaces are *ignored* in regexes, so
you actually end up with $/[0] eq ' Test'. Use the <.ws> rule to avoid
this. (The leading dot prevents that whitespace from additionally being
captured as $/<ws> which here would be pointless. You might also want one
before the literal open paren so you don't also eat any spaces there.)
#!/usr/bin/perl6
my $x='sub Test () { #`(Sub|63218616) ... }';
$x ~~ m/sub <.ws> (.*?) <.ws> \(/;
say "$x\n$0";
