[Activerdf] A resource or an array as returned object

[Damaris Fuentes]

Hi you all,
  I've realised (I dunno if this is the normal behaviour or I am doing something wrong) that if I ask for a set of resources with a property, the method returns either a resource or an array, depending on the number of objects obtained.
   
  If a say:
  dcsubject = RDFS::Resource('http://purl.org/dc/elements/1.1/subject')
@stuff = dcsubject.rdfs::seeAlso
   
  and the "seeAlso" returns more than one resource, @stuff is an array with these elements. However, if the "seeAlso" property relates the subject with just one resource, "@stuff" is this resource. 
  So I cannot use the "for resource in @stuff do.." always. I just have to initialize @stuff as @stuff = [], and then add the possible resources, or just distinguish with an "if" clause if @stuff is one element or an array. Wouldn't it easier if the method returned always an array, even with one element? 
   
  Thanks :D
