Walter, try this:

	class Window
	{
		import windows;
		HWND hWnd = null;
	}

Error: "non-constant expression cast(HANDLE)(null)".

When I cast it explicitly, the error is the same. HWND
is an alias for HANDLE, and HANDLE is typedef'ed
as void*. If you make HANDLE alias rather than typedef,
it works.

typedef needs work :-(

Then maybe it would be wise to make HANDLE alias for now? So that programs at least work... =)

Yes. Consider typedef broken for the time being.

By the way, the bug seems even more strange. You CANNOT cast null to a HWND:

	const HWND hWnd = cast(HWND)(null);	// doesn't work (with or without cast)

But you CAN cast zero to a HWND:

	const HWND hWnd = cast(HWND)(0);	// works!!!

Maybe something's wrong with null?

I'll check it out.
