I'd like to slightly restate the differences like:

#eql? -- Equivalence with type and value
#=3D=3D -- Equivalence with value
#equal? -- Identity

I'd like to interpret calling coerce as a comparison based on values
while ignoring types. Hence, 2.eql? 2.0 is false because their type is
differnt,
while 2 =3D=3D 2.0 is true because their value is the same though their hav=
e
differnt
types.
