[racket-dev] Search by example (was Re: Roogle?)

There isn't a way to do that, no.

But I think in Racket we have better ways of avoiding such danger
(namely using the sandbox library or the pieces it builds upon). In
general, in fact, you'd have to do that anyways, since a contract can
be some arbitrary predicate (and don't forget do-dads like #:pre and
friends).
