That's what I do without thinking much about it.

Going off topic a little, Phobos has something to offer for such Yes/No 
flags:

import std.typecons;

struct Foo
{
     Flag!"with_int" a;

     this(int y)
     {
         this.a = Yes.with_int;
     }
}

Yes.with_int is a convenience struct. Otherwise, you can type 
Flag!"with_int".yes and Flag!"with_int".no as well.
