Bizarre:

void main()
{
    int i;
    auto dg = delegate ref() @safe => i;

    alias DgFull = ref int delegate() pure nothrow @nogc @safe;
    alias DgAuto = typeof(dg);

    pragma(msg, DgFull); /* int delegate() pure nothrow @nogc ref @safe */
    pragma(msg, DgAuto); /* int delegate() pure nothrow @nogc ref @safe */
    pragma(msg, is(DgFull == DgAuto)); /* true; okay */

    alias DgSafe = ref int delegate() @safe;

    pragma(msg, is(DgFull : DgSafe)); /* true; okay */
    pragma(msg, is(DgAuto : DgSafe)); /* false; wat */
}

`DgAuto` actually also has the attributes`scope` and `return`, but they have a special "inferred" marker. That means they're not printed.[1] Apparently, the marker also has an effect on `is(X == Y)`. Still bizarre.
