Hi !

Is there such a magic ?

struct S { uint k = 2; }

enum Value = Foo!(S.k); // Value == 2

Thanks.

struct S { int k = 2; }

enum Value = S.init.k;

static assert (Value == 2);

Oh i see, thanks

But what about the case when default ctor is disabled ?

Only relevant if you've written something like `@disable static S init();`, which you shouldn't be doing anyway. `.init` is independent of `@disable this()`
