I write my function signatures like this now and I'm fine with
the change:

@safe pure nothrow @nogc [<1]
final override @property ref [<2] int foo() shared const [<3]
{
   ...
}

[1] Attributes that hint the compiler by narrowing down
    allowed language features.
[2] Visibility and behavioral attributes.
[3] Modifiers for implicit `this`.
