    Hi all,

    Should the evaluation of:
    ``(,',@(loop for arg in '(a b c) collect `(cons ',arg ,arg)))

    Be:
    '((cons 'a a) (cons 'b b) (cons 'c c))

    CMUCL and SBCL return `((cons 'a a)).

    I've distilled this example from one of the macros I have written that has
    returned unexpected results. Before reporting this bug I just want to
    check that my example is portably defined ANSI Common Lisp code and the
    result CMUCL and SBCL returns is not conforming.

    Thanks,
    Adam
