This post presents an interesting way to make error handling more brief in Golang 1.18

One of the downsides to this approach is that defer functions and catching panics can be generally more expensive than using if/return for error handling. I decided to benchmark to see how significant the penalty turns out to be.

For some boilerplate, we have a giveError function:

func giveError(b bool) (int, error) {
  if b {
    return 0, fmt.Errorf("given error")

	import random
	import parsley

	def roll(x, y, k=None):
	k = k or x
	if k > 0:
	s = slice(0, k)
	else:
	s = slice(k, x)
	return sum(sorted((random.randrange(1, y+1) for _ in range(x)), reverse=True )[s])
