Subject: Iterators within Madeleine

I'm currently stumped in how to implement iterators within the
confines on a Madeleine environment. It's very easy to just expose the
entire instance with all its variables; but I want to build an "each"
to be run via the "execute_command" method in Madeleine. Is this
possible?

A scenario using the dictionary server sample program would be:
To access the key/value pairs iterative via "each" within the confines
of full concurrency protection.

Therefore, at the client, I should be able to do:

  dictionary.each { |key,val|
    print "key=#{key}, val=#{val}\n" # read access
    dictionary[key] = val + "foobar" # write access
  }

On top of that I should be able to do the above with multiple clients.

Is the above feasible or am I dreaming??... :-}
