 Sorry to say this but this is the most common error that I see when
 someone try to eval some code with $SAFE >= 4

 The code will be eval'ed with $SAFE >= 4 but the result (#value) will be
 used with $SAFE = 0 and you can have problems.

 The result of #eval must be cleaned with $SAFE >= 4, before it's
 returned.
