Subject: optparse examples

I have a question about the optparse examples at
http://docs.meg.nu/local-docs/ruby/optparse/optparse.htmlWhat does the
following do ?if (Fixnum === :-)
  class << vars
    def inspect
      "{" + collect {|k,v| ":#{k.id2name}=>#{v.inspect}"}.join(", ") + "}"
    end
  end
end
and then this line which is commented out: #opts.variable.each {|sym| puts
"#{sym} = #{opts.send(sym).inspect}"}Looks like some kind of debug code, but
I thought if I understood it itshed some light on things in general.
