           Summary: @safe forces bounds checking on newly allocated array
                    when using .ptr
           Product: D
           Version: D2
          Hardware: x86
                OS: Mac OS X
            Status: NEW

          Severity: enhancement

```
void main () @safe
{
    auto ptr = [ 42 ].ptr;
}
```

This errors out, even tho it is perfectly @safe.

```
foo.d(3): Error: [42].ptr cannot be used in @safe code, use &[42][0] instead
```
