good example of assert as expression ?

[user1234]

Following a [previous 
thread](https://forum.dlang.org/thread/loojkahtbzigawrscmsr@forum.dlang.org), can you give me good example where the assert expression is useful ?

So far I only see the case where it is used as AndAnd RHS.

```d
void main()
{
     auto lhs()
     {
         extern(C) int rnd;
         return (rnd % 1) + 1;
     }

     lhs() && assert(0);
}
```

I remember an old NG topic where someone asked if D supports the 
"assert idiom".

So seriously assert as an expression just works in this context ?
I mean don't you think it's an obscure feature that could be 
removed ?
