in reply to Two-arg open() considered dangerous

Dake Desu... cannot remember my pass, seeing as how I have not made a mental mnemoric for it yet, and I cannot check my email for it at school (Never write your passwords down).

How 'bout 
$filevar ~= s/>/>/g;
open FILE, "<mode>$filevar" or die "Could not open file: $!";

If an end user decides to add those ">" to the variable, and be generally evil, it will blow up in their face...

Also adds some security for CGI, if your doing something like a forum ^_^.

Ps: I will never get use to HTML in forums ^_^

    Two major points off for your comment:
    1. Replacing ">" doesn't address "|" or leading spaces.
    2. Re-inventing HTML::Entities -- poorly -- is stupid.

      You left out the meta point-off for "don't write down your passwords; send them in clear text through email."

      Update: This appears to be my 100th post. w00t!
