 Well I have a working work-around that I need to test further, 
however it does the job; Although for other applications it may 
fail miserably on, and has very limited application.

template bitfieldsOn(string storeName, T...) {
  enum bitfieldsOn = "mixin(bitfieldsOn_b!(\"" ~ storeName ~ 
"\"," ~ storeName ~ TupleToString!(T) ~ "));";
}

template TupleToString(T...) {
  static if (T.length)
    enum TupleToString = "," ~ T[0].stringof ~ TupleToString!(T[1 
.. $]);
  else
    enum TupleToString = "";
}

so this makes...
  mixin(bitfieldsOn!("bits",
    ulong, "back",  32,
    ulong, "", 32));

and becomes:
  mixin(bitfieldsOn_b!("bits",bits,ulong,"back",32,ulong,"",32));
