From 77678b2cbc7ac9ba2d5d4725241f6a9f7ac64fa4 Mon Sep 17 00:00:00 2001
From: Andrew Kelley 
Date: Sun, 10 Jun 2018 01:13:51 -0400
Subject: breaking syntax change: orelse keyword instead of ?? (#1096)

use the `zig-fmt-optional-default` branch to have zig fmt
automatically do the changes.

closes #1023
