@ -439,11 +439,11 @@ Rails 4.1 now expects an explicit block to be passed when calling
`ActiveSupport::Callbacks` being largely rewritten for the 4.1 release.
```ruby
# Rails 4.1
set_callback :save, :around, ->(r, block) { stuff; result = block.call; stuff }
# Rails 4.0
# Previously in Rails 4.0
set_callback :save, :around, ->(r, &block) { stuff; result = block.call; stuff }
# Now in Rails 4.1
set_callback :save, :around, ->(r, block) { stuff; result = block.call; stuff }
