  well...  apart from wanting to avoid the first recursive function call
  (which can be done with a simple iteration from a lower limit to the
  value in question, but this is not something I want the compiler to
  decide for me), optimizing fibonacci is mostly a matter of memoizing.  it
  _would_ be useful if a compiler could see that there is no way a function
  would return a different value if given the same arguments, i.e.,
  automated detection of side-effect-free functions and various means of
  propagation of this information.
