Since the following are both true:
int[] a = null;
int[] b = [];
assert(a is null);
assert(!a.length);
assert(b is null);
assert(!b.length);
What I would like is to tell that b is an empty array and a is
a null

Hi all
I end up with a directory flooded with platform probes. How can I

Thanks

What is an opCast ?
operator overload of the cast function. if you didn't write one,
you don't have to worry about this.

A DWORD_PTR is *not* the same as a uint. It is more like a size_t
or void* depending on context.

As a general question, what is the purpose of ModuleInfo,

you need to specify that you want to cast to a pointer of type T.

No. A class reference is a pointer under the hood. Getting its

alias this only applies if you already have an object.
Construction is too soon.
You can add a constructor to make that work though.
