It isn't that easy. There are differences between fib and fastfib:

  (%i11) [fastfib(-44),fib(44)];
  (%o11) [6765,701408733]

Also fastfib(x) --> error and fib(x) ---> noun form. And fib modifies
the global prevfib. All these issues need to be resolved.

I can think of other fib related things that could be done
too---interaction with floor and ceiling, using recursion relations to
simplify expression involving Fibonacci functions, and converting fib
to a simplifying functions. These things take time.
