The docstring says

  This is like ‘equal’, except that it accepts numerically
  equal numbers of different types (float vs. integer), and
  also compares strings case-insensitively.

Just so many to keep track of ...

Also `eql' which works like `eq' only also "works" for
floats ...

  (eq  1   1  )  ; t
  (eq  1.0 1.0)  ; nil

  (eql 1   1  )  ; t
  (eql 1.0 1.0)  ; t

  (eql -0.0 0.0) ; nil (uhm, how does that situation appear?)
  
  (*   -1   0.0) ; -0.0 (okay ...)

  (=   -0.0 0.0) ; t (the same position on the axis of real numbers)
