  Evaluate (excl::explain-compiler-settings) and turn on the various
  :explain options.  The amount of output even exceeds CMUCL at its worst,
  but it can be very helpful in realizing when and how to declare stuff.

  What were the types of variables in the C version?  How much time does a
  function call usually take?  Do you have an example?
