But when you made it, you were smart enough to put some error conditions that would either 'die' or 'croak' with Carp when things occurred that would prevent it from doing anything further (file not found, file not readable, etc) as well as the occasional carp that complains about things it finds that aren't quite kosher.

Out of curiousity, couldn't you:

	use readcfg;
	my $cfg;

	eval { $cfg = new readcfg(-cfgfile => 'somefile.cfg'); };

	if ($@)
	 {
	  # danger Will Robinson, handle the exception
	 }
	 else
	 {
	  # all is well in configuration land ...
	 }

I seem to remember doing something like this in DBIx::SimplePerl and others.
