eval is the wrong answer since it can run arbitrary code

If the user gives you some form of # rm -rf * ~ / , a lot of your files get deleted

    The OP said nothing about a user supplying the string. We pointed out that there are security concerns if you don't trust the string.

    If you want to run arbitrary code supplied by a 100% trusted source at runtime, what would you use other than eval?
