There is this trick as workaround:

```
auto valueToString(alias v)(){return v.stringof;}
enum a = valueToString!(0.75);
static assert(a == "0.75");
```

The problem with to() and format() is that is requires external 
library calls that are not available at compile-time, just like 
when you try to use malloc() at CT.
