Yeah, it looks like dmd on 64 bit will emulate the old shitty way that was
"natural" for dmd on 32 bit. But I don't understand why you would WANT to do
that. Why emulate something broken and hard to use? Passing an array of void*
to each parameter (see _argarray in issue description) would be so much easier.

Not sure what you mean by that. There's no RTTI for struct members, so this
would be very not-useful. You'd still need to pass _arguments, and you'd still
need to follow the ABI for the struct layout (granted, better than trying to
follow the stack layout).
