Consider the following code:
import std.typecons;
struct Struct
{
Nullable!int ni;
}
void main()
{
Struct a = Struct.init;
Nullable!Struct b = Nullable!Struct(a);
}
test.d(6): Error: variable `test.main.__copytmp756` `inout` variables can only be declared inside `inout` functions

[This works now in stable again, as long as T - int in this case - doesn't have a copy ctor.]

Oh I see, this fix was not merged into master?

Likely; important uncontroversial fixes go to stable first and do make it to master at some point.
