Error provides you a generic and extensible framework to handle errors, but it won't do
exactly what you're looking for.
You basically need a method of retrying, which can be handled as
BrowserUk states, or, based upon your code - can be something like:
# CODE NOT TESTED
# for display purposes only
# void in Utah
my $rc = undef;
my $i = 0;
do {
$rc = go_to_web_page();
}
while ( !$rc && $i++ < 3 );
or, perhaps, using Error
# CODE NOT TESTED
# for display purposes only
# void in Utah
my $i = 0;
GET_PAGE:
while ( $i < 3 ) {
try {
go_to_web_page();
# the above has to throw some kind of error
# for this to work
last GET_PAGE;
}
catch Error with {
$i++;
};
}
I'm sure there's a cleaner way to do that, but it's just an example off the top of my head (proof of concept).
