Not that Ali is wrong in the full sense, but this line alone will
compile on both 64 and 32-bit systems, so it is not informative.
However, the fact that assigning it to `ulong.max` doesn't work coupled
with this means that it's 32-bit.
You can use code like this to tell you what your platform bits are:
```d
pragma(msg, cast(int)(size_t.sizeof * 8), " bit");
```
