Retry is a Perl module that provides a method to wrap any function in automatic retry logic, with exponential back-off delays, and a callback for each time an attempt fails.

Example:

 my $agent = Retry->new(
 failure_callback => sub { warn "oh dear, error: " . $_[0]; },
 );
 eval {
 $agent->retry(
 sub {
 this_code_might_die();
 }
 );
 };
 if ($@) {
 die "We totally failed!";
 # Note that if we succeeded on a retry, this won't get called.
 }
