1. Any proposals to mark a function as CTFE only?

In OpenD you can

```
string genStuff(string val) {
        if(__ctfe) {
                return val ~ ";";
        } else {
                assert(0);
        }
}
```

That is, wrap the whole function in `if(__ctfe) {}` and it 
passes this test since the gc use is now provably only in ctfe.

I don't know about the other dmd release but it might work 
there too, worth trying it.

This idea worked with DMD64 D Compiler v2.111.0.

In particular, it worked even when the equivalent of 'genStuff()' 
was defined in a different module and imported into main.

Thanks!
