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)
