   Unsafe evaluation
     Proof of concept:
       It is never safe to eval() user input, plain and simple.  There is always another way to skin the cat; try and consider that!
     
     Mitigation:
       Design around combining the function "eval" with user input.
     
     Auditing:
       IGNORECASE=1 find -regextype posix-awk -regex ".*\.(rb|php|pl|py|pm)" -exec grep -HnC2 \\beval\( '{}' \;
