The ability to eval a string can be useful in generating code from a
template at run time, among other things. Of course, those who want to
cram tainted ``supercalifragilisticexpialidocious'' input from GOD
knows where into an eval statement, should just be shot, hung, drawn,
and quartered - no need for a legal opinion before hand.

There is no such thing as a feature that is absolutely always wrong to
use, just brain damaged people to use it inappropriately ;). Just look
at the TOPS family...
