alias this is for implicit conversion, which requires an object to
convert

Thanks for this pointer. It was very helpful to read it as it confirmed that I
was going doing the right thing in my code. That you have two sources adding
some interleaving is
Is it possible to overload a function template for rectangular
arrays? Is there any way to tell them apart from normal ones?
void foo(T)(T[] a) {}
void foo(T)(T[][] a) {}
auto ra = new int[][](5, 5);
ra.foo(); // matches both
Thanks for any hints.

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

No. A class reference is a pointer under the hood. Getting its
address will result in a pointer

Possibly, it is just that the documentation is sadly lacking in examples of

Where is DWORD_PTR defined? I cant find it in docs. If its an
alias of long then you have to cast to a pointer like this
cast(long*) this;
you need to specify that you want to cast to a pointer of type T.

it is a win32 thing. should be able to directly cast to it most
the time
if there is opCast on the class it needs another layer of helper
function but without opCast it should just work

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

Hello,
As a general question, what is the purpose of ModuleInfo,
constructing and deconstructing each of the runtime's modules? In
other words, what are the ramifications of using gdc's

Since the following are both true:

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
