Regardless of how the value `f` is initialzed, this style
has a problem: The initial value of `f` is discarded. I think
that discarding values shall be avoided.

Thus I write the initialization:

```d
   float f = (...) ? 1 : 2;
```

Compiler warnings/errors like "Defined but not used" are known for
variables. Is there a similar facility for values?
