Hello. I apologize if I missed something.
I found strange behavior in ruby 1.9:

 class Custom < Array; end
 Custom.new(0){|i| i + 1}.uniq.class # => Array
 Custom.new(2){|i| i + 1}.uniq.class # => Custom

while in 1.8 it works just as I expected. 

 class Custom < Array; end
 Custom.new(0){|i| i + 1}.uniq.class # => Custom
 Custom.new(2){|i| i + 1}.uniq.class # => Custom

* it is actual not only for the uniq method.
* tested with ree-1.8.7-2010.02, ruby-1.9.2-p290, ruby-1.9.3-p375, ruby-1.9.3-p125

Any bug here?
