Instead of the `tie` assignment, you can just do:

And here I was trying to use comma expressions for this like a
buffoon! Of course they didn't work, but I'm pleasantly surprised
that using a sequence does. I should really PR `std.typecons` to
add a couple of examples of this, because I think a lot of people
will have overlooked it.
I honestly thought there was no way to do this in D for the
longest time until I saw some C++ code using `std::tie` and I
realised that obviously the same thing is doable in D using
`opAssign`, and then refined it to use UFCS because the syntax
`Tie!(y,x)()` was a bit clunky.
