```
auto w = 01777777777777777777777;
```

```
Error: octal literals `01777777777777777777777` are no longer 
supported, use `std.conv.octal!1777777777777777777777` instead
```

It's worth a try:

```
auto w = std.conv.octal!1777777777777777777777;
```

```
Error: integer overflow
```

Quote from `std/conv.d`:

```
template octal(alias decimalInteger)
if (is(typeof(decimalInteger)) && 
isIntegral!(typeof(decimalInteger)))
{
     enum octal = 
octal!(typeof(decimalInteger))(to!string(decimalInteger));
}
```

Does it *feel* wrong to you, too?
