Actually, I was claiming that if there's a problem there, then it's one you already have. The reasoning I used is just that eval() can call a foreign function, which can re-enter Hugs. My patch added no new code paths (as I said before). Perhaps there *are* problems with existing primitives which call eval(), but you need to check those anyway.
