Great, thanks - so something like the code example from here
<http://mojolicio.us/perldoc/Mojo/IOLoop#delay>? Not sure how to replace
the timer with recurring logic though
# Synchronize multiple eventsmy $delay = Mojo::IOLoop->delay(sub { say 'BOOM!'
});for my $i (1 .. 10) {
my $end = $delay->begin;
Mojo::IOLoop->timer($i => sub {
say 10 - $i;
$end->();
});}
$delay->wait;
