Shorthand alternative for respond_to

If you have a simple respond_to block in your controller that looks like this:

respond_to do |format|
  format.html
  format.xml
end

You can use this alternate syntax and save a few keystrokes..

respond_to(:html, :xml)

Ok so it may not give you a huge performance boost, but if you’re obsessed with reducing the size of your code, this is a nice way to make a saving!
