This definitely isn't allowed in C or C++. I wonder what the

An hypothesis is that this makes codegening the pre and the post
variants almost identical. The only difference is what is yield.

Now there's not much to say about the topic, I just thought it
was amusing to share that (user1234 is my noname nickname here)

In the same vein you have the possibility to select an lvalue
with a conditional expression. Pretty sure nobody knows that the

```d
int a,b;
int c = rand();
((c & 3) ? a : b) = 42;
```
