do..end vs curly braces for blocks in Ruby

Question

I have a coworker who is actively trying to convince me that I should not use do..end and instead use curly braces for defining multiline blocks in Ruby.

I'm firmly in the camp of only using curly braces for short one-liners and do..end for everything else. But I thought I would reach out to the greater community to get some resolution.

So which is it, and why? (Example of some shoulda code)

context do
  setup { do_some_setup() }
  should "do somthing" do
    # some more code...
  end
end

or

context {
  setup { do_some_setup() }
  should("do somthing") {
    # some more code...
  }
}

Personally, just looking at the above answers the question for me, but I wanted to open this up to the greater community.

There a few points of view on this, it's really a matter of personal preference. Many rubyists take the approach you do. However, two other styles that are common is to always use one or the other, or to use {} for blocks that return values, and do ... end for blocks that are executed for side effects.
