Great question.

`reinterpretcast!T` is just ugly. I never liked it in C++. `cast(ref T)`, on the 
other hand, looks nice.

We've seen other aesthetic improvements in D, such as:
```
int square(int x) { return x * x; }
```
becomes:
```
int square(int x) => x * x;
```
and other shortened syntax for lambdas, and the `if` declaration variant.
