my $t = Thread.new(    name => 'My thread',    code => sub {        say 'Hi there!';    });

The thread is now created but is not activated. To run it, the run method must be called:

$t.run();

Execute the following example and examine the order, in which the lines appear on the screen:

my $t = Thread.new(    name => 'My thread',    code => sub {        say 'Start';        sleep 2;        say 'End';    });say 'Before';$t.run();say 'After';

As soon as the thread is running, it prints its two messages, Start and End, separated by a delay of 2 seconds:

BeforeAfterStartEnd
