I have the following code:

my $obj = MyStupidString.new;

What am I misunderstanding here?
The `xx` operator. That's list-repeat, not string-repeat.
In Perl 5 terms, the code you wrote is:
sub repeatit {
my ( $string, $repeat ) = @_;
my @res = ( $string ) x $repeat;
print @res;
my $add = "@res";
print $add;
}
which should make it obvious what is going on.
Thank you and Juerd.
It was indeed a misunderstanding, I though "x" changed to "xx" in Perl6
for some reasons...
Now is the first time I write some Perl6 code that I actually run, too
:) It is *really* enjoyable. Feels like "this is how Perl should really
look like", and it is so DWIM I can hardly believe it. Kudos to all who
helped to make it happen!
