RCR 153: const_missing should be invoked before toplevel scope is sea

This is a legacy RCR from Ruby Garden, submitted by pong. Matz has declared these RCRs obsolete, and asked that their authors resubmit them in the new format.

If you define const_missing and you refer to a constant using an explicit scope like this M1::Object then M1::const_missing should be invoked before searching the toplevel scope.

module M1

  def self.const_missing(aSymbol)
    puts "Looking for #{aSymbol}"
   end

end
M1::Blah # Prints "Looking ..."
M1::Object 

1. Returns :: and ruby prints the warning:
2. "warning: toplevel constant Object referenced by M1::Object"

I don't even understand why this is a warning in the first place, it should be an error, imho. And since ruby knows when to print the warning it should be straightforward to consult constant_missing first/instead.
