case syntax and symbols

[Aaron VanDevender]

Hello,

I have noticed that guile evaluates the following to #t

(case 'x
  ('x #t)
  (else #f))

even though R5RS section 4.2.1 seems to say that all of the statements
(besides else) must be of the form ((datum ...) ...). Clearly the symbol
'x is not a list. What is going on here? Is this an agreed upon, but not
specified syntax? Scheme48 also evaluates this to #t.
