You don't need begin unless you want to catch just a section of code. Single
lines works wonders for concise error handling, such as

this_method_can_throw rescue "default value"

Or for a full method (Rails)

def action
  does_stuff_that_can_throw
rescue
  default_error_handling
end

Ruby's awesome.
