[rspec-users] Spec failing [Possible Bug with kind_of? and instance_of?]

[Jerry West]

Answer written in haste, so may well be wrong...

Rails associations are not Arrays even though they claim to be.  I think  
they are ActiveRecord::Associations::AssociationProxies; why they claim to  
be Array I have no idea, simply being Enumerable would have sufficed I  
would have imagined.  Why they proxy an array rather han extending it I  
have no idea.  I have very few ideas :-).  I personally believe proxies  
that lie to the developer like this should Be Considered Harmful, but it's  
not my opinion that counts in this particular piece of opinionated  
software :-).

I haven't yet worked out how to tell an AP from an Array.

Hope this helps.  Hope I've remembered correctly too!

Rgds,
   Jerry
