I did say we subclass Nagios::Plugin, so the code you see in my code
that calls ->opts->get('timeout') is calling your methods as I extend
your module.  I am not reimplimenting nor repeating code you have
done.  If you look at my module Nagios::Plugin::SNMP on CPAN you will
see I don't reinvent any wheels you have already made :).

This still doesn't make sense to me over having a simple wrapper
around timeout in Nagios::Plugin so the user doesn't have to call
alarm($n->opts->timeout) in their code every time they want to do a
timeout instead of doing


which would also then make it easy to let the user override a default
$SIG{'ALRM'} handler by passing a reference to a function in to either
new() or to the wrapper function, e.g.

    sub { my $secs = $plugin->opts->get('timeout');
             $plugin->exit(CRITICAL, "Timeout of ${secs} seconds breached!");  }
