Hi list,

it seems that display is very loosely specified, resulting in implementations
outputting

((lambda (lambda) `(,lambda ,'lambda)) '(lambda (lambda) `(,lambda ,'lambda)))

or

((lambda (lambda) (quasiquote ((unquote lambda) (unquote (quote lambda)))))
(quote (lambda (lambda) (quasiquote ((unquote lambda) (unquote (quote
lambda)))))))

or even

lambdalambdaquasiquoteunquotelambdaunquotequotelambdaquotelambdalambdaquasiquoteunquotelambdaunquotequotelambda

when running

(display ((lambda (lambda) `(,lambda ',lambda)) '(lambda (lambda) `(,lambda
,'lambda))))(newline)

I'm not sure if it is intentional to allow all these forms. Perhaps the
specification of display can be clarified to explicitly (dis)allow such a wide
range of variation.
