Define CASE, CCASE, ECASE to be comparing using EQL

[phoe]

This is an omission in the standard. It states that Since eq is used only rarely in this specification, eql is the default predicate when none is mentioned explicitly. but CASE, CCASE, ECASE allow the conditional execution of a body of forms in a clause that is selected by matching the test-key on the basis of its identity. where the term identity is not defined. Common sense and examples state, though, that EQL should be the "official" predicate.
