// eval and the Function constructor throw Node's EvalError, exactly as
// under node --disallow-code-generation-from-strings (the harness runs the
// Node oracle with that flag): catchable, at call time, after the
// arguments evaluate. The Function constructor converts its arguments to
// strings before it refuses; eval refuses without converting.
