class CGI
  def [](x)
    [x]
  end
  def export(args)
    args.each { |arg| self[arg][0] }
  end
end
    
cgi = CGI.new

p defined? name   # => nil
p defined? email  # => nil
p defined? phone  # => nil

name, email, phone = cgi.export %w(name email phone)

p name    # => "name"
p email   # => "email"
p phone   # => "phone"
