I'm actually still trying to get my head around operator+ invoking

My bad. Sorry to confuse the issue Herb.

  I should have used the "apply" function name
that we actually use. (Comes from trying to
work and monitor this list at the same time.)

  either

  template<typename A, typename B>
  typeof(A + B) apply(A &a, B &b)
  { return a + b; }

  or

  auto apply(A &a, B &b)
  { return a + b; }

would work.

I prefer the "auto" version as I won't make mistakes
duplicating the expression. (In this case the expressions
are simple so its no problem.)
