Eval

Out of curiosity, why is eval considered evil 
. The hits I find with an internet search are pretty much all java & perl, so what is a problem to ksh?
I try to avoid it, but there are occasions where I can't find another sensible way. I understand the cost of another process, especially if it's used in a loop, but is it dangerous.
Thanks, in advance,
Robin
