Is there complete code somewhere? I can’t get the examples to
compile beyond the first one and the rest elide re-used
sections beyond the first.
I wanted to include a shortlink from run.dlang.io, but that seems
to be broken now and I can't create one. Here's a gist:

I lied a little bit in the article - `static assert` doesn't
actually work in this case because opDispatch swallows errors,
and instead you get a "no member for type..." message. That's
really annoying, but it's more or less necessary because of how
opDispatch works. I wish we had a better solution.
