Because it seems that some people really needs binary literals 
and can't work without them although there are many higher level 
alternatives.

Binary literals aren't efficient (too many digit to represent 
relatively small numbers) and aren't essential to the language 
itself (hex literals are far more efficient). If you need to set 
flags an enum approach makes code much more readable:

```d
enum MyFlag {A = 0, B, C}

T asFlag(T)(in T f) pure @safe nothrow @nogc{
   return (1 << f);
}

...

int field = MyFlag.A.asFlag & MyFlag.B.asFlag;
```
