I have the same thing in my code:

```d
enum intStr(int x) = x.stringof;
```

The reason you do this is to shoehorn things that aren't technically 
ints (such as enum types) into ints. This avoids weirdness like 
`cast(foo)bar` or whatnot that might happen if you just use stringof on 
any expression.

Yeah, I wouldn't worry about stringof for ints.
