Les De Ridder has implemented the druntime function and made 
phobos use it for its move function, all thats left is to make 
the compiler insert a call to it when it moves structs around.

That would go here:


you'd need one for 
as well

Would probably want to insert the call in, Razvan Nitu would 
probably know better/in more detail.

This should be no problem, all that is needed is to insert a call 
Its all front end stuff, i.e. LDC will be able to use whatever 
the front end does with no problem.

I'm humbled, but a bit busy. Don't let me stop you opening a PR 
though. I'm sure Razvan and I can try to help you there.
