Great idea. I would like to propose a couple of tiny changes though.
Your code:
sub time {
my $obj = shift;
my $delay = shift;
if (defined $delay) {
$obj-> cancel if $delay == 0;
$obj-> [2] = $delay;
} else {
$obj-> [2];
}
}
If it were up to me, I would change the code to this:
sub time {
my $obj = shift;
my $delay = shift;
if (defined $delay) {
if ($delay =~ /^\+?\d+$/) {
$obj-> cancel if $delay == 0;
$obj-> [2] = $delay;
} else {
carp "argument must be a non-negative integer";
}
}
$obj-> [2];
}
Changes:
1) Make sure $delay is a a non-negative integer. If not, throw a warning.
2) Return the delay in all cases.
Just my two cents,
