I'm doing some code cleanup and need to replace the old

is_domain_name

function from stdlib and running into issues that don't make sense. I'm trying to use

stdlib::validate_domain_name()

to validate something that used to work and it is claiming that it is invalid an an

if

class bar {                                                                                                     
  $domains = [

  $domains.each | String $domain | {                                                                            
    if $domain =~ Stdlib::Fqdn {                                                                                
      notify { "${domain} is a Stdlib::Fqdn": }                                                                 
    } else {                                                                                                    
      notify { "${domain} is NOT a Stdlib::Fqdn": }                                                             
    }                                                                                                           
    if stdlib::validate_domain_name($domain) {                                                                  
      notify { "${domain} is a stdlib::validate_domain_name": }                                                 
    } else {                                                                                                    
      notify { "${domain} is NOT a stdlib::validate_domain_name": }                                             
    }                                                                                                           
  }                                                                                                             
}

when I run it through

pdk test unit

, I get these resources

Notify[<http://dept1.example.edu|dept1.example.edu> is NOT a stdlib::validate_domain_name]
  Notify[<http://dept1.example.edu|dept1.example.edu> is a Stdlib::Fqdn]

  Notify[<http://sub.dept2.example.edu|sub.dept2.example.edu> is a Stdlib::Fqdn]

I thought the whole point of

stdlib::validate_domain_name

was to check to see if it was either a Stdlib::Fqdn or a Stdlib:Dns:Zone type. What am I missing?
