Can not figure out how to load 'perl' file from 'config.rep'
also in SYNOPSIS $class is undefined. There is error that I can not call
config on undefined value.
my $cfg= Config::Any->load_files({ files => [ 'fire.rep' ],
force_plugins => [ 'perl' ] });
for (@$cfg) {
my ($filename, $config) = %$_;
my $class->config($config); #ERROR HERE: $class is undefined
print "loaded config from file: $filename";
}
