Fair enough about chroot... but there still isn't a reason to NOT use 3-arg open() - is there? Especially when the user input is untrusted.

As per the OP's latest node, if they use:

open (FILE,  "$path")

[download]

(rather than $docroot$path or whatever) then a client could request a $path of ">important.file" which could (depending on permissions) clobber the important file. Using the 3-arg open() suppresses the "special" interpretation of the first character.
