With D 2.063 the follwing code no longer compiles:

import std.json;
import std.typecons;

void main()
{
    JSONValue value = void;

    value.type = JSON_TYPE.NULL;
    Nullable!JSONValue(value);
}

phobos/std/typecons.d(1178): Error: cannot implicitly convert expression
(value) of type JSONValue to inout(JSONValue)
test.d(9): Error: template instance
std.typecons.Nullable!(JSONValue).Nullable.__ctor!() error instantiating

Without the recently added 'inout' in 'this()(T value) inout' of 'struct
Nullable(T)' it used to work.
