How to separate business logic from exception handling

separate.rb

def run_with_exception_handling
  begin
    puts '1'
    yield
    puts '2'
  rescue Exception
    puts 'Exception thrown'
  end
end

def test_runner
  run_with_exception_handling do
    raise 'boom'
  end
end

test_runner

Any method can take a block in Ruby. There is no syntax required in the method defined to accept a block. The test_runner method can call the run_with_exception_handling and focus only on the business logic. The exception handling method can catch and handle specific exceptions that are recoverable by retries, non-recoverable and user errors separately.
