even better and simpler way

You should look into the purpose behind taint checking before proceeding. Some of this eval() stuff can be dangerous! Imagine... blindly executing anything that a user types as input to a perl script! And if you don't get it, think about some of perl's builtin functions that don't do math. Like unlink(), maybe?
