The fact that you can't extend low-level system "things" (classes or interpreter data structures) in either ruby or C# is my point. In smalltalk - you can modify the VM with smalltalk. Avi exploits this fact to add continuations to Squeak so that Seaside can support very sophisticated flow control. This is an extremely low level system modification - and one that is trivial in smalltalk. I’m not suggesting that Ruby’s and c#’s array classes are equivalent.

Ruby's Array is equivalent to the C# ArrayList, the C# array is a low-level system class, and isn't extensible just like you can't directly access most interpreter data structures in Ruby.
