First link is broken, second doesn’t lead to what’s claimed.
Can you tell me what the problem is for you when you click the first link? I tried to make it work for all browsers (even mobile, but the UI isn’t very mobile friendly), so I would like to get it working on your system too. If you can give me a bug report (and maybe try from different system), that would be great.
The second link explains:
x += yandx = x + y: https://github.com/bterwijn/memory_graph#name-rebindingIt’s left to the reader to generalize this to
x |= yvsx = x | y.Diagnostics came up with some “double percent-encoding” issue on IOS. I’ve updated the website with a workaround, hopefully it does work now. Thanks for bug reporting.
