It wouldn't change eval.

Neither cgi-lib.pl nor CGI.pm will have any effect on builtin functions
such as split().

Are you sure that the string ends with a newline when you split it?  If
your string is more like "a\tb\tc\t\t\t", then you _will_ get 3, because
split() drops trailing null fields by default.

I think that's asking too little.  You should be able to run it without
changing any lines at all!
