But that doesn't give the desired result, as I said, using CGI#header
in this way also prints out the content-type header - which CGI.pm
doesn't.  You would want:

class CGI
  def redirect(url)
    "Status: 302 Moved\nlocation: #{url}\n\n"
  end
end

which would then be used as similar to CGI.pm:

print cgi.redirect('http://location.com/')

You would also have to consider that the above is incompatible with
the way the header handling works under mod_ruby (header is sent
straight away rather than returned, I think).

I agree with you that the way you can 'dip in' to existing classes
from anywhere in ruby is great, but I still think CGI#header should be
in the standard cgi.rb, as it's very commonly required.
