I'm still quite curious why `with` is not entirely in the body like `cond`
and `case` and so forth is (ditto with `for`), so it'd be:
```elixir
with do
%{x: x} <- y
x
end
```
It follows the pattern of cond and so forth, no weird comma's needed, no
weird prefix `do:` or so forth, you only need to split on `<-`, etc....
