IMO, that is a mistake.  The lesson we learnt from the previous
experience with overloads is that they tend to break code which were
previously valid or has well defined semantics in C.

  #include <math.h>

  int main()
  {
    return !cos(2);
  }

Use resticted templates -- and the code tends to be the same anyway.
