The way I'd do it is:

S s;

auto heap = new S;

*heap = s;


that should work.

auto ps = std.conv.emplace(new S, s);

Avoids the hacky array aliasing.

That constructs S two times.

// slightly more efficient
auto ps2 = emplace(cast(S*)(new ubyte[](S.sizeof)).ptr, s);

You will need to define a copy constructor for immutable fields.

That should work but it's rather complicated.
