When you want a compile-time binding that could potentially elide the
indirect function
Hello,
Why this doesn't work:
```d
template DestructorType(T){
alias Get(T) = T;
alias DestructorType = Get!(typeof((void*){
T tmp;
}));
}
struct Foo{
~this()@safe{}
}
```

void main(){
//Error: static assert: `is(void function(void*) pure

I had no clue, never seen it used in any case. I've always
assumed one couldn't return void as it's not a value. I guess
intuitions aren't always universal . Good to
