Set *print-circle* to t.

Wasn't it Donald E Knuth who said that?

I've seen it attributed to both, and I've seen it formulated
differently (all on the ever-accurate wonderful world wide web), but
I'd admit to not being sure.
More authoratative references would be appreciated, but until then
I've modified my sigmonster file to say:

I have no knowledge of the truth on this one one way or the other.
It will be weirdly ironic, though hardly uniquely so in CS, if it is
Knuth. His life's work seems to be about optimization, and I daresay
it's led directly to some curious evils, viz, TeX qua programming language.
(Mind you, I've used TeX many a time, but I'd say it plainly suffers from
an overemphasis on efficiency at the price of clarity and debuggability
all over.)

Sorry about being off-topic...
"Premature optimization is the root of all evil."

Knuth extensively cites Hoare in his article, but not for the statment
in question.
