I had one suggestion which I think was lost in the recent gateway
debug process... I'll repeat it again below - hopefully it wasn't a
simply bad idea :)

To me, creating multiple instances of initialized objects feels like
it belongs more with the new call, rather than Integer. Perhaps we
could add a "multiple instance" new? Here is one implementation.

def Object.newx( nx, *args)
  instances = []
  if( block_given? )
    nx.times { instances.push yield(self.new(*args)) }
  else
    nx.times { instances.push self.new(*args) }
  end
  instances
end


a,b,c = Array.newx(3)

I'm not sure what should be done when the new also expects a block.
